In the meantime, I am doing my blogging at another website. I just did a post over there about some handbuilt work using Georgie's Crystal Springs porcelain. It's been good to work with as long as I don't rush the drying. <br />
<br />
Here's an image of one of the pots I build and decorate in the blog... please have a look if you are interested.<br />

The goblet pieces needed a couple of days to dry slowly under plastic.<br />
<br />
Here's a nice stem ready for trimming. I have several small Dolan trim tools that make this easy. The base of the stem is still massive and solid, and I like to detail the stem before hollowing out the base,<br />
<br />
I've gone to some pains to keep the small cup at the top moist since most of the problems I've had in the past have to do with two two segments not joining up properly.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

Here's that same base with some trimmed details. If your stem is not centered carefully, it's hard to get nice results. You can see the little Dolan trim tools in the photograph.<br />
<br />
Just as soon as I get it shaped, I moisten the interior surface of the upper cup with a wet finger, and stick a piece plastic over it.<br />
<br />
<br />

<br />
Here's another nice stem ready to use. I will probably do just a bit of carving on some of the elements of the stem.<br />
<br />
Now, it's time to trim out the foot.<br />
<br />
I attach the vase that I made with the goblet components to the wheelhead. This is a carefully thrown sacrificial piece that will be used as a chuck to trim the bases of the stems.<br />
<br />
I want it to be quite moist, so the stem will stick to it during the trimming process. I adhere the chuck to the wheel securely with fat coils of clay.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgsKayxGsJregz0Pa0XcxY1OUv9qfG-rn9kVQYFomoH97ulkyC4vEaCEEzr5ZR5tnF9SNJuWlbMy1BgT_gzjrAAmPZXm729W6wGR92qPRkSlnaoyYjaaorrVBmRrF_R81KDUJ_9_U-SUeg/s1600/IMG_3333.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgsKayxGsJregz0Pa0XcxY1OUv9qfG-rn9kVQYFomoH97ulkyC4vEaCEEzr5ZR5tnF9SNJuWlbMy1BgT_gzjrAAmPZXm729W6wGR92qPRkSlnaoyYjaaorrVBmRrF_R81KDUJ_9_U-SUeg/s320/IMG_3333.JPG" width="260" /></a></div>
When you make your chuck, take care to make the top opening wide enough to accommodate the top of your stem.<br />
A chuck like this can be use to trim bottles, small ewers, and many other pieces that are fragile or difficult to trim.<br />
<br />
When the stem is well centered in the chuck, you can begin to trim. I use the same small tools to hollow out the foot.<br />
<br />
You can see how crude the base of the foot is when trimming begins.<br />
<br />
I like to trim the out portion of the foot very carefully, so the goblet will sit flat. It takes some concentration for me to hollow the foot. I almost always feel that trimming takes much more attention than throwing, but that is probably different for each potter.<br />
<br />

There's a lot of torque on the base as you trim, so moderate your wheel speed carefully. <br />

Here's a finished stem ready to use. There is nice form detail on the stem, and the the base is appropriately sectioned for drying.<br />

Now, for the joining.<br />
<br />
With the cup portion of the goblet attached to wheelhead, score its' base and also score the interior of the cup at the top of your stem.<br />
I like to add a blob of nice thick slip to fill any voids in the space that might be created.<br />
<br />
Position the stem upside down on the base and turn the wheel slowly. You will be able to see if the stem is correctly positioned. If it is plumb and centered there will be no wobble at all if the wheel turns. <br />
<br />
You will have a little time to adjust the position - the slip helps with that.<br />
<br />
<br />

It's been a long since my last post, but I continue to receive emails from potters who have found it useful.<br />
<div>
<br /></div>
<div>
Today I am working in the studio to fill a kiln for Holiday sales, and wrap up a few small special orders. Although I don't make goblets as part of my production work for shows and galleries, I have some in my studio and visitors see them and want to purchase them. At this time, only a few chalices are left - just the thing for toasting your Dungeons and Dragons compatriots! </div>
<div>
<br /></div>
<div>
To me, a chalice is deeper and has a shorter stem in proportion to the overall height of the piece. Buyers prefer more traditionally formed goblets with tall steps and capacious bowls. I think ceramic goblets sort of take away half the joy of wine drinking - seeing the beautiful color of the wine through a crystal vessel. Therefore, let's use them for mead or hard cider or best of all, a delicious hot toddy....</div>
<div>
<br /></div>
<div>
I like to make goblets in two parts and join them. Both sections are thrown off the hump. The clay I am using today is B-Mix, which has many fine properties. However, it will be the last day for it in my studio for a while... I am going back to Georgies' Cannon Beach 10. </div>
<div>
<br /></div>
<div>
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgvrZg5uPYiumwTcr19W9nUgl9gkeCN8fkF-JoqDe-LyYxQUYA1hoHEwWvQbvPQk7Y0VqzJGZCQjW7W1qd8ug-L9KSr2Rh7vZe0tTYSBObEq3WKdCKyqOwQTc6pP29qmTVq-O6VZK8KFhs/s1600/1+Off+the+Hump.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgvrZg5uPYiumwTcr19W9nUgl9gkeCN8fkF-JoqDe-LyYxQUYA1hoHEwWvQbvPQk7Y0VqzJGZCQjW7W1qd8ug-L9KSr2Rh7vZe0tTYSBObEq3WKdCKyqOwQTc6pP29qmTVq-O6VZK8KFhs/s320/1+Off+the+Hump.JPG" width="275" /></a>I'm starting off with about 5 pounds of clay - enough for about 6 bowls and fairly thick stems. If you are not making small pieces - lids, knobs, small tea-bowls - off the hump, I really encourage you to learn to do so. </div>
<div>
<br /></div>
<div>
The only complex part is separating the object from the hump in a tidy and level manner. I struggled with this for years until Portland potter Ken Pincus kindly showed me how to do it the right way. If I can find a friend to shoot a little video of me doing this tiny but essential trick, I will post it here in the next couple weeks. </div>
<div>
<br /></div>
<div>
In the meantime, we'll stick to the goblet making....</div>

Here's what we want to make. It's crude! But it is closely thrown and well centered. The fun part - refining the stem and adding ornament will come during the trimming process. With a toothy stoneware clay it is possible to do more preliminary forming of the stem, but the slickery B-Mix - pretty wet, also - wasn't willing.<br />
<br />
It's important to keep downward pressure on the top of the stem as you bring it up so it isn't hollow. If you have been throwing spots on the wheel, it's counter-intuitive. <br />
<br />
There is also that big, thick base. I'll trim that out later so them stem is light and balanced.<br />

Here's a shot of the top of them stem. A small rice-bowl shape is thrown into the top of the stem. <br />
<br />
I usually cut the top of the stem off level with my string tool so that this tiny cup - about 1-1/2" in diameter - is perfectly symmetrical and dead level. The separately thrown bowl will nestle into this cup. <br />
<br />
Like a spout, there is movement during the firing that can "unwind" the form. If all is not level, your goblet may come out of the firing with a tipsy appearance that it just not acceptable.<br />
<br />
Drying the stem carefully under plastic is simply essential. The thin little top must remain fresh and moist so it will join properly to the cup.<br />

<br />
Here's a nice prospective bowl for one of the goblets. I usually make 6 or 8 stems and the same number of bowls and match them for scale and form when I do the joining.<br />
<br />
I will dry them separately, and trim the bottom of each on to match the stem-top cups, then use a serrated rib to scuff them up, and mate the trimmed stem to the cup right on the wheel head. <br />
<br />
With the wheel in motion, it's easy to see if the stem and cup have been matched correctly, and repair any "wobbling" that is the sign of an out-of-plumb join.<br />
<br />
I'll show all this later this week with photos from the join-up.<br />

<br />
This taller piece is one of the most essential parts of the process - a chuck for trimming the base of the stems. <br />
<br />
I'll detail the shaft of the stem right side up, with the heavy base stuck to the wheel head with coils of clay.<br />
<br />
Then, I'll insert the stem into this chuck upside down so the base is supported. The chuck was carefully thrown to be well centered, and was not cut off the bat. It may live to become a vase, but might also just be recycled.<br />
<br />
I find it hard to trim out the inside of the stems but they will crack if the wall section is not reduced carefully. The crack would be up inside, typically an S-crack, and won't spoil the pot. But why not do it right?<br />

I have been busy with other clay projects, daily work at my nursery business, and with learning to use my new salt kiln. <div>
<br /></div><div>As you may recall from previous posts, my other kiln was deteriorating badly and needed a rebuild. With the help of co-workers from my nursery who have worked as masons in Mexico, I designed and cast the firebox, door, and arch of my new kiln. The body of the kiln was built of hard brick, with a soft brick shell for insulation. There is a much better metal superstructure than was built for my previous kiln, thanks to my brother Don who is a great welder.<div>
<br /></div><div>First the good news - the new kiln is vastly more efficient and faster firing. It will reach cone 10 in about 14 hours, and I think it will do even better as I learn to fire it. But after just 4 firings, the cast refractory arch will have to be broken out and replaced with a hard brick arch. We just did not cast it as thick as it should have been, and the stainless steel reinforcing rod was consequently laid in too close to the interior surface. In the very first firing with ware in place - there had been a s-l-o-w curing fire as specified by the manufacturer - the arch cracked right down the center, and debris sifted onto the pots on the top shelf.</div><div>
<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgLSR_P_kfJRw7S559fnF2djwzpqVC1JEwgzN8_F4PrfnGvcCfaw_iG8Og9W6-XcXaCckfzaN7O5cYWLcZrlK9rMuLjnIY1IIIvoTz_s9qtQVpq83HEKmBOO8ll3wj9oPq6RSKGm0JT8Lc/s1600/Arch+Damage.JPG" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgLSR_P_kfJRw7S559fnF2djwzpqVC1JEwgzN8_F4PrfnGvcCfaw_iG8Og9W6-XcXaCckfzaN7O5cYWLcZrlK9rMuLjnIY1IIIvoTz_s9qtQVpq83HEKmBOO8ll3wj9oPq6RSKGm0JT8Lc/s320/Arch+Damage.JPG" border="0" alt="" id="BLOGGER_PHOTO_ID_5643458946567252306" /></a>It's apparent from the image how the rebar has broken through the refractory material. It's going to be a nasty piece of work breaking out that arch. I have the original arch form, a big tile saw with a new blade, and those same guys who built the cast arch to help out. </div><div>
<br /></div><div>You can see below how I set a shelf in the top of the kiln to collect the crud that same down from the cracked arch.... better than spoiled pots. I was hoping to get one more firing before Art In The Pearl, but it is not too be - it was just too badly cracked after the last firing.</div><div>

I like to apply patterns to my clay while it's flat and helpless... much easier than individually incising whole pots. I also think that teapot users like the funky, vaguely irregular bodies of handbuilt teapots. And of course, I really like to make them - the only real reason to do anything.<div><br /></div><div>I had thrown forms related to this quite a few times and knew the scale and proportion that I wanted to achieve. </div><div><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj3Bs4n3pUCQhF-Wqs1lN_9i3B-4kJj7xrJwtu1Bh1aWfrLTYZGOO_t_UEvXHsmbue-C6kNEDM-wBqqpwxZw4fA9LClr8xoGRszvqWGPv2Cc4oTja3j8WNUiEGpB3xH9hJp3Qee3D_dYeY/s1600/Dry+the+Block.JPG" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 258px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj3Bs4n3pUCQhF-Wqs1lN_9i3B-4kJj7xrJwtu1Bh1aWfrLTYZGOO_t_UEvXHsmbue-C6kNEDM-wBqqpwxZw4fA9LClr8xoGRszvqWGPv2Cc4oTja3j8WNUiEGpB3xH9hJp3Qee3D_dYeY/s320/Dry+the+Block.JPG" border="0" alt="" id="BLOGGER_PHOTO_ID_5607369859440308610" /></a>First, the clay has to be conditioned to be at the correct stage of dryness for cutting, decorating, and building. I undress the block of clay the night before, and leave it out for 4 or 5 hours, depending on whether or not I have a fire in the studio. In summer, it takes much less time. I just want to be sure that the clay is stiff enough that it won't collapse when I start assembling my forms. It's also much easier to do the stamping, rolling, and other surface decoration when the clay is a bit firm.</div><div><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg0wIgaOhtLcZ3_iCKn5o3TfzcU4-w1IZj7kObNK7wAYu-_sMr51tP_ts7wlmtMF5Z3VbPC7mWatxIT3daCy_P8UfEVVSaVWknMKVK74utNn55NiqOAtnaQ6EUOs3_uqEPPkTP6dbm8ttg/s1600/Cut+to+Slab.JPG" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 320px; height: 242px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg0wIgaOhtLcZ3_iCKn5o3TfzcU4-w1IZj7kObNK7wAYu-_sMr51tP_ts7wlmtMF5Z3VbPC7mWatxIT3daCy_P8UfEVVSaVWknMKVK74utNn55NiqOAtnaQ6EUOs3_uqEPPkTP6dbm8ttg/s320/Cut+to+Slab.JPG" border="0" alt="" id="BLOGGER_PHOTO_ID_5607369856575285970" /></a><br /></div><div><br /></div><div><br /></div><div>The next morning, I cut the block of clay into 3 or 4 slices so it can dry further, and will be easier to put through the slab roller.

I am using stiff sheet PVC for my patterns - permanent and durable for studio use. On the pattern pieces, I will record the name of the piece, how many pieces there are, and assign a number to each piece. That really helps for storage and retrieval.

I thought in the early years that I might get 100 firings, but the condition of the kiln is beginning to concern me and it's clear that it's time to rebuild the kiln. This has been a problem kiln since I first completed it - lots of desire for the salt process but not enough knowledge to build the kiln properly. Basically, there's just too much hard brick in the kiln. There were a lot of stalled firings in the first year, and then I kinda got it figured out and was able to get it to Cone 10 in about 14 hours. Those were the good days.... sigh. But then, I changed propane suppliers and they changed the regulator on the tank, and a frustrating period began with terrible long firings that barely reached temperature. There was a lot of BAD SCIENCE on my part - and my need for work for shows and galleries kept me from doing anything serious to remedy the situation.<div><br /></div><div>I might have gotten my 100 firings if it hadn't been for the many long stalls, hours and hours over 2000 F with temperature barely creeping up.

I have also extruded 1/2" coil to use for the knob shanks, and have carefully cut it to 1/2" lengths. It's firming up as I press the sized balls into the mold cavities. I am going to throw a little tool to press the ball into the mold and mark the center of the knob blank. My clay (Georgie's Cannon Beach 10) joins to itself really well, so I just score the shank bit with a serrated rib and center it on the back of the blank knob. After the shaft is joined to the knob, I wait about 5 minutes and they can be lifted out with the shaft.

That way, the sleeve will be flush with the bottom edge of the drilled hole, and will not vanish into the knob if the hole is deeper than the brass bit.

It's essential that chucks be perfectly centered so that you can make the most regular knob possible. I like for the clay to still be wet enough to still be slightly sticky when the chuck is used. That way, the object being trimmed stays put on the chuck, but it also means that it is really easy to ding up the top of the chuck.

Most of the tile is complete, and some is installed. In my dining area, there are beautiful new oak cabinets that will have a tile counter top and back splash. I want to make ceramic knobs for these cabinets. I first saw handmade ceramic knobs at the home of my potter friend Ted Juve, in Enterprise, Oregon. Ted explained to me exactly how to make them, and gave me a small bag of the threaded brass inserts that complete the knobs.<div><br /></div><div>I made my first knobs about a month ago, and cast them in plaster to make a press mold, so that I could make as many as I needed. The first knobs I made were too deep, and had to be hand cut after forming. I decided to make a new batch to carve and cast in plaster, and include this fun process in my blog. <div><br /></div><div><br /></div><div><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgmIUIJikw0M0qM3xXeKAI6MJVU84Fi6snRuCQ5AR08_VUiYhgNlQRAIg9faSIxURlkomQCWpuPc3pI91XhBHuiiWCeeLhzfV8m4ehn4sNcCGGMCovYJ6_jPvzuV0I6-eITZ0g-8OUW174/s1600/IMG_0023.JPG"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgmIUIJikw0M0qM3xXeKAI6MJVU84Fi6snRuCQ5AR08_VUiYhgNlQRAIg9faSIxURlkomQCWpuPc3pI91XhBHuiiWCeeLhzfV8m4ehn4sNcCGGMCovYJ6_jPvzuV0I6-eITZ0g-8OUW174/s200/IMG_0023.JPG" border="0" alt="" id="BLOGGER_PHOTO_ID_5568372987670817794" /></a>I started out to throw some new knob blanks off the hump with my regular stoneware clay. I brought up a narrow column of clay, and formed a small knob with my fingers that was about 2 inches across. I added a little dimension to it, based on which of the first knobs I liked. The idea is that these new knobs will be just about the size that I want the finished knobs to be, accounting for shrinkage, so that I can just cut the knob to the finished size with a wire while it is in the press mold. I plan to shape the sides of the knob blanks when I trim the knobs in a tiny chuck later in the process. This will eliminate any undercut that might complicate the plaster process.</div><div><br /></div><div>You can see that I am cutting the the small knob off the hump of clay with a thread tool. This is a small bamboo knife - about 5 inches long - with a hole drilled in the rounded end. Then, a piece of stout linen thread (buttonhole twist from the fabric store also works....) is threaded through the hole and tied. I like about 6" of thread. </div><div><br /></div><div><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgLdtVITm60Gm4BTOkjf1wwGfyZVicDUYWKRwJHr-Sg5tBPCM7dc8kg8YlMnArLG5P3PSIJdbVRBew-uyjB_8ytPpFg26WYYtKSF6AgcPYL0z7wDzMvqKZzDncWqtmnwu1oL2w5cyw3oYI/s1600/Moving+Knob.JPG"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgLdtVITm60Gm4BTOkjf1wwGfyZVicDUYWKRwJHr-Sg5tBPCM7dc8kg8YlMnArLG5P3PSIJdbVRBew-uyjB_8ytPpFg26WYYtKSF6AgcPYL0z7wDzMvqKZzDncWqtmnwu1oL2w5cyw3oYI/s200/Moving+Knob.JPG" border="0" alt="" id="BLOGGER_PHOTO_ID_5568372014845691650" /></a>I use the bamboo clay knife to place the knob blank on a board to dry a bit for trimming.</div><div><br /></div><div>These knobs are finished by adding a 1/2 inch plug of clay at the back, and drilling a hole about about 1/2 inch deep into the extension to make a shaft to receive a threaded brass sleeve after firing.

I'm going to be making a door surround for my front door - a 12"-14" border that will wrap both sides and the top of the door. I will also be making decorative tiles, back cove, and <span class="blsp-spelling-error" id="SPELLING_ERROR_0">bullnose</span> molding for a kitchen tile installation. I made most of the field tile about six years ago - about 80 square feet. A big new kitchen window and some new cabinets in my kitchen are a serious incentive to complete the project.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">I have a slab roller, <span class="blsp-spelling-error" id="SPELLING_ERROR_1">extruder</span>, and glaze spray booth, all of which will be used to complete the tile. Because my <span class="blsp-spelling-error" id="SPELLING_ERROR_2">pugmill</span> is filled with the high-fire clay that I use for my production salt-fired pottery, I will not have the luxury of <span class="blsp-spelling-error" id="SPELLING_ERROR_3">recycling</span> the tile clay with the <span class="blsp-spelling-error" id="SPELLING_ERROR_4">pugmill</span>. I'll be working hard to keep waste clay to a minimum in my process.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">Here's a picture of my slab roller and it's attached table, with work in progress. I like to roll my tile out on Slab Mat, a paper product made for the use of potters. I used to use canvas, but always wanted to take the canvas texture off the tile. The Slab Mat also reduces clay dust in the studio, which is good for me and my dog.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">You can see lots of boards around the table... there are 12" x 24" drywall boards for separating and preliminary drying of the tile. There are also 24" x 24" boards which I use for moving tile around and for final drying.</div></div></div><div style="text-align: left;"><br /></div><div style="text-align: left;">I've been making tile for about 15 years, but continue to learn. My process is pretty much based around the equipment I own, and I know that there are many ways to make beautiful and functional tile. Years ago, I attended a tile making workshop presented by Frank <span class="blsp-spelling-error" id="SPELLING_ERROR_5">Georgini</span>, and I still consider his tile-making book to be one of the best available.</div><div style="text-align: left;"><br /></div><div><div style="text-align: left;">The first step in making tile, for me, is to get the bagged clay to the right stage of dryness. I check the bag of clay, and if there is any sheen of visible moisture, I open the bag and allow the clay to dry a bit right in the bag.</div><div style="text-align: left;"><br /></div><div style="text-align: left;"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjXxPliNCXPeapulhULXWvP-6YU8GtkKvig1PpbrvaO59VKae3LGcuJkeCeZiG1PJXHNqZCSR2BHHkRZeIgbx46dtPoll5ngytQYTTfMcCeZrp_sq_7urYHNkpFa_P59S4ib2a9gKmMw84/s200/DSC05019.JPG" style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 150px; height: 200px;" border="0" alt="" id="BLOGGER_PHOTO_ID_5519372814555122578" /></div><div style="text-align: left;">I will be using a low-fire talc body for my tile project; one with which I have had lots of experience. Because I have used Seattle Pottery <span class="blsp-spelling-error" id="SPELLING_ERROR_6">Supply's</span> <span class="blsp-spelling-error" id="SPELLING_ERROR_7">LF</span>-06 for a number of projects, I have several glazes that fit it very well. I have found the tile that I have made with it in the past to be durable. And, because winter temperatures are mild here in western Oregon, and since my new front door is tucked back under a covered porch and will not be exposed to the weather, I think that the low-fire tile will be fine for an outdoor installation. I will bisque and glaze fire both to Cone 04.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">I use a large clay cutter to divide the block of clay into 3 even slices. Here, you can see two bags of clay cut and set on edge to dry. I like to work with clay that is as dry as possible. The drier your clay is when you roll and cut it, the fewer "dings" that there will be on your tile to remove later. The clay should be much, much drier than any clay that you would throw on the wheel. </div><div style="text-align: left;"><br /></div><div style="text-align: left;">It's a good idea to keep track of how you divide your bag of clay. When making tile, a potter should work toward forming slabs that have the smallest amount of waste possible. The stiff tile-making clay is simply no fun to wedge for reuse. </div><div style="text-align: left;"><br /></div><div style="text-align: left;">I cut my block into thirds, then stretch the stiffened blocks to exactly 15" long. When the 15" block is turned crosswise in the slab roller, and thinned to 1/4", I get 6 tiles that are 7.5" square with less than 1/2" of waste on each side. I worked all this out after making over 500 tiles of the same size for a mural installation at a local school. Right now, I am just making about 100 tiles for accent use. The main tiles for my kitchen job are 4" square.</div><div style="text-align: left;"><br /></div><div style="text-align: left;">In my next post, I will go into some of the techniques I use to make flat, regular, tiles. I know that sounds deadly dull, but it makes the tiles more beautiful and serviceable, and much easier to install.</div><div style="text-align: left;"><br /></div><div style="text-align: left;"><br /></div><div> </div><div><br /></div></div>Ginger Steelehttp://www.blogger.com/profile/02859169181773574347noreply@blogger.com2tag:blogger.com,1999:blog-2992770042811485395.post-76582980518974108262010-03-06T09:01:00.000-08:002010-03-06T09:59:36.289-08:00Making a Handbuilt Spout<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjXna8YCahYAt0y1EohAJRqKHLXP7jHZZrLj4_3VoZfnmLu7Ucmd973nIX1BmlVcAaiih_op0jFxd-f-uPKkAK9QhJNY6dAqapDDrl8ayWBpuXRjnjxBr91Tz5EE4o6y2M7mfKo9EGmRJQ/s1600-h/1+Spout.JPG"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 200px; height: 110px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjXna8YCahYAt0y1EohAJRqKHLXP7jHZZrLj4_3VoZfnmLu7Ucmd973nIX1BmlVcAaiih_op0jFxd-f-uPKkAK9QhJNY6dAqapDDrl8ayWBpuXRjnjxBr91Tz5EE4o6y2M7mfKo9EGmRJQ/s200/1+Spout.JPG" border="0" alt="" id="BLOGGER_PHOTO_ID_5445568714906665010" /></a>First, a template is used to cut conditioned clay into a conic spout-shaped form. The clay is softer than what I use for most handbuilding - this will permit the spout to be curved without any cracking of the clay. The clay should be just a tiny bit over 1/8" thick. When a wheel-thrown spout is made, the wall section naturally tapers from the bottom to the top. To replicate this thinning of the spout wall, I use a dowel to roll a small taper into the entire spout, thinning the top 1/3 of the spout just a bit. After this secondary thinning, I again trim the spout blank with the template. <div><br /></div><div>This will help to make a more refined pouring tip possible later in the process. The template has been made by trial and error - rolling my wooden mandrel on the sheet PVC I use for patterns - and then using the side of the mandrel as a straightedge. I do make the attachment end of the spout a bit wider than the natural size of the mandrel. The template is about 10"long. The best mandrel I have was made of oak by a potter in Eugene, Dan Schmidt. I believe he went away to ceramics grad school.... correct me here, Eugene blog-followers. The Big Ceramic Store on line sells a mandrel but the proportion isn't right. I have had some made by a local woodturner that I use for my workshops.<div><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg_-gZJpxGI8pkNozXGRAqb2LmUVmVbzg67HI6jDCKgovTBFCIjLWxvEL8ldrmoKgdGBW7zbN7AW344gg1iqcNY-weczSQijSrvlCax0pyeIqZbqVcb-TOas0emhlyKk8DgnY3ghzOP33U/s1600-h/2+Spout.JPG"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 200px; height: 124px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg_-gZJpxGI8pkNozXGRAqb2LmUVmVbzg67HI6jDCKgovTBFCIjLWxvEL8ldrmoKgdGBW7zbN7AW344gg1iqcNY-weczSQijSrvlCax0pyeIqZbqVcb-TOas0emhlyKk8DgnY3ghzOP33U/s200/2+Spout.JPG" border="0" alt="" id="BLOGGER_PHOTO_ID_5445568703209121602" /></a>Using the brayer, I thin and bevel both long sides of the spout blank. This allows a neat, thin join to be made. It's good to thin and bevel in several passes, working in opposite directions and making an effort not to distort the spout blank.

This takes a little practice. It's okay if your mandrel doesn't extend all the way to the tip, you can use your fingers to press the tip into a neat join. Do not cut the tip at this point or try to shape it. That can be done much more easily quite a bit later, even after the spout is placed on the teapot.</div><div><br /></div><div><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOJflwr7DqpTZ-spzTFaYGyXET4OuejKms1lsXYhmAGMK80El6LsXOIDGOS1v33eiAimokC03Oha91Nn-sHpXzdtwJyi94OgxOdyfWyj51CiZhyphenhypheni8VkG6c0EICr9RnlSbUvOneEeAC4G4/s1600-h/5+Spout.JPG"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 200px; height: 116px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOJflwr7DqpTZ-spzTFaYGyXET4OuejKms1lsXYhmAGMK80El6LsXOIDGOS1v33eiAimokC03Oha91Nn-sHpXzdtwJyi94OgxOdyfWyj51CiZhyphenhypheni8VkG6c0EICr9RnlSbUvOneEeAC4G4/s200/5+Spout.JPG" border="0" alt="" id="BLOGGER_PHOTO_ID_5445568222515357362" /></a>Here's a pic of a stage in spout making where proper alignment of top and bottom edges can be seen.

What you see in the image is about right for the teapot bodies I will be making. You will have to experiment with your own forms. I usually make spouts the day before I make teapots, and allow them stiffen slowly. I like to put them in a plastic shoe box, cushioned in dry cleaner plastic, with the lid on tight. It is possible to join a pretty soft slab to a teapot body, but I can get a neater look with a spout that has "rested" a while.</div><div><br /></div><div><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhyz0D9_YrXvGyBg29ztrsEPPNgOjhmQwKx3bhqWtBtaRhNjcaVBRZUx65fkI3ZCiz1BapsuNBoHHRuQbr7mr6CF3Tp6gQF6mVutThzCl_sBWct0bsYBzYuWMj1fROSI1ARYRvkln3CdhI/s1600-h/15+Spout.JPG"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 104px; height: 200px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhyz0D9_YrXvGyBg29ztrsEPPNgOjhmQwKx3bhqWtBtaRhNjcaVBRZUx65fkI3ZCiz1BapsuNBoHHRuQbr7mr6CF3Tp6gQF6mVutThzCl_sBWct0bsYBzYuWMj1fROSI1ARYRvkln3CdhI/s200/15+Spout.JPG" border="0" alt="" id="BLOGGER_PHOTO_ID_5445567643934046258" /></a>When the teapot body is ready, the spout will be cut with a single long stroke and joined to the body.

I tried about three times to do this with appalling results, gave up, and started handbuilding spouts with the mandrel as an aid. At that point in my clay career, I couldn't pull a handle either, so maybe I should try again.</div><div><br /></div><div>I have seen Steven Hill pull a spout on a pool cue sprayed with WD-40.

White earthenware clay - <span class="blsp-spelling-error" id="SPELLING_ERROR_0">LF</span>06 from Seattle Pottery Supply - was used to build these pieces. Participants worked with conditioned clay slab, stamps, rollers, and texture mats to form and decorate their pieces, and all pulled handles on their teapots after practicing handles on their cups. We all decided to call the process "handle smoothing" instead of "handle pulling".</div><div><br /></div><div>I'll be posting the whole teapot making sequence on the blog in the next week or so. In the meantime, here's the low-fire glaze recipe that we talked about during the workshop and saw on pieces in the studio. This is an extremely well behaved, <span class="blsp-spelling-error" id="SPELLING_ERROR_1">paintable</span> <span class="blsp-spelling-error" id="SPELLING_ERROR_2">Gerstley</span> <span class="blsp-spelling-error" id="SPELLING_ERROR_3">Borate</span> glaze that comes from Gail Kendall. It should be thick and <span class="blsp-spelling-error" id="SPELLING_ERROR_4">goopy</span> - about the consistency of yogurt, and is easy to paint on pieces. I like to use one of those <span class="blsp-spelling-error" id="SPELLING_ERROR_5">cheapie</span> disposable brushes from Home Depot, but any wide flat brush with coarse bristles is fine. </div><div><br /></div><div>You can paint this glaze inside a cup fairly easily, but it is a problem to get it inside teapots or tall pieces, or very small pieces. I use Georgie's <span class="blsp-spelling-error" id="SPELLING_ERROR_6">lowfire</span> base glaze for pouring inside pieces. I am not sure if this glaze is still available, but every pottery supply house offers a dry <span class="blsp-spelling-error" id="SPELLING_ERROR_7">lowfire</span> clear. These glazes are often hard to dip on smoothly, and sometimes have unpleasant opaque areas where the glaze is too thick. The Georgie's base glaze is very nice sprayed on the outside of pieces, but I could never get a good surface by dipping or pouring. But it makes a great liner glaze, and is completely compatible with Kendall glaze. Over or under, the two glazes melt together smoothly. Here's the recipe:</div><div><br /></div><div>Kendall <span class="blsp-spelling-error" id="SPELLING_ERROR_8">Paintable</span> 04 Glaze</div><div><br /></div><div>55% <span class="blsp-spelling-error" id="SPELLING_ERROR_9">Gerstley</span> <span class="blsp-spelling-error" id="SPELLING_ERROR_10">Borate</span></div><div>30% <span class="blsp-spelling-error" id="SPELLING_ERROR_11">EPK</span></div><div>15% Silica</div><div><br /></div><div>Rich Green - 8% Copper Carbonate</div><div>Cobalt Blue - 2.5% Cobalt Oxide</div><div>Inky Blue - 6% Copper Carbonate + 1.5% Cobalt Oxide</div><div>Rich Yellow - 6% <span class="blsp-spelling-error" id="SPELLING_ERROR_12">Rutile</span></div><div>Cream - 3% <span class="blsp-spelling-error" id="SPELLING_ERROR_13">Rutile</span></div><div>Warm Clear - 1.5% <span class="blsp-spelling-error" id="SPELLING_ERROR_14">Rutile</span></div><div>Ochre - 7% Umber</div><div>Medium Blue - 2.5% Cobalt Carbonate</div><div><br /></div><div>Mason Stains - 4% typical, more required for all pink, purple, red</div><div><br /></div><div>The "Cream - 3% Rutile" variant is what was used on the pieces seen in my studio.</div><div><br /></div><div>This glaze should be thick! If you try to thin it enough to pour, it will not yield a satisfactory surface. I paint three thin, even coats on each piece, taking special care under handles and around details. It will crawl if it is too thick.

I am making a latex texture mat, which has text and imagery that will be incorporated into a funereal reliquary. The reliquary will be used for the ashes of two much-loved and exceptional people, husband and wife, who requested that their remains be joined after their deaths and interred at a wild and beautiful spot on the Oregon coast. These two individuals were Floyd George Steele, and Dorothy Jane Petersen Steele, my father-in-law and mother-in-law.<div><br /></div><div>The design of the imagery records their shared, lifelong appreciation of music, and F. G.'s passion for mathematics. D.J. loved plants and flowers, and enjoyed having them in her home. The names of their six children are part of the design.</div><div><br /></div><div>The imagery will be incised into a 1/2" thick slab of white, grogless, low-fire clay. I like Seattle Pottery Supply's LF06 for this use. Like all talc bodies, it is a pain to recycle, but has many other fine properties. The slab was cut to the largest dimension that will fit into my Skutt 1227 kiln. Once the imagery is complete, the slab will be carefully dried before bisque firing to Cone 04. After firing, a 2-part latex mixture will be applied in three coats, and a mat will be lifted. This mat will be used to texture a slab for the body of a reliquary, and can then be used to create keepsake pieces for family members.</div><div><br /></div><div>In the image at the top of the page, you can see a quilter's oval template laid out to align with a center mark on the clay.

What you can't see is that my right hand is in a container of water. First, I use my wet thumb to refine the join area at what will be the top of the handle. Then, I dip my hand in water, and then begin to stroke and smooth the handle blank. I am not pulling it downward- that will happen as the blank is wetted and smoothed. The hand doesn't want to make a symmetrical handle - it isn't a symmetrical apparatus itself - so differential pressure will have to be used to each surface of the handle. I really don't know how to describe that... you will have to experiment. This does take practice - I started really understanding how to do it after a long workshop with Ellen Shankin, where many, many handles were attached. Before beginning to work the handle, I wet and scored an area at the base of the cup where the handle tail will be attached. I did this to create a target for placement, as well as to strengthen the eventual join there.<div><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjgLRMxUm47exIQE9QgIg3kbO9Iwiyx2FsLBbRtbqCPO8-9lAqBDGizs1bEHgQoMPf11qlP2H2OHQf71Byprt3ZOpyi1hReKaYd8EVqvOIHDeCc85XYsjNwYWjhCPkJhTtYCaPB-T8bGUM/s1600-h/DSC03738.JPG"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjgLRMxUm47exIQE9QgIg3kbO9Iwiyx2FsLBbRtbqCPO8-9lAqBDGizs1bEHgQoMPf11qlP2H2OHQf71Byprt3ZOpyi1hReKaYd8EVqvOIHDeCc85XYsjNwYWjhCPkJhTtYCaPB-T8bGUM/s200/DSC03738.JPG" border="0" alt="" id="BLOGGER_PHOTO_ID_5439596692352340754" /></a>Now, you can see that how the handle has lengthened and thinned as I have smoothed and shaped it with my wet hand. At this point, you can add a groove with your thumb if you like that look. Don't be afraid to experiment! I almost always have an inch or two of clay to pinch off at the end. If you should need to reattach a new handle stub, scrape the top of the cup smooth and set it aside for a little while. The cup clay with be softened from the first attachment, and it will need to stiffen a bit. If the handle stub has been properly prepared, this shouldn't happen.</div><div><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6ZZSPWK2SI2dZrKjavxT8v1KLE__WDrMPaoC9L82_hDORJBPCUXLtNr4zSJqEVyBOMsnSjb9bQdpme2z-ibTZSbcvz8KgCCGhxTcoOq2p9JlVMH6aJkfJ2u9kb7RfmKJbd6V7mXTr04E/s1600-h/DSC03739.JPG"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 150px; height: 200px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6ZZSPWK2SI2dZrKjavxT8v1KLE__WDrMPaoC9L82_hDORJBPCUXLtNr4zSJqEVyBOMsnSjb9bQdpme2z-ibTZSbcvz8KgCCGhxTcoOq2p9JlVMH6aJkfJ2u9kb7RfmKJbd6V7mXTr04E/s200/DSC03739.JPG" border="0" alt="" id="BLOGGER_PHOTO_ID_5439596689397060802" /></a>Here's the cup and handle ready to finish.

Potters, this can be learned easily with practice.<br />Start with some nice, fresh clay - not reclaim. Roll out a fat coil about 1.25" in diameter for these big mugs. If your clay starts to flatten out, twist each end in opposite directions and it will roll round again.<br /><br /><br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhKkNYxZlTFEg2zfCNtPan5VpsDfhvr9Y-lqs7-srKrHfZ9XPITJ_IPymmjnslhvvdrGLIRmZPU1FVtia_2ms9APPOpDk8jk3EOl1DwYDX_X5uGIWrHUKefIok8bBV6xtR4k4LXgPH710E/s1600-h/DSC03732.JPG"><img id="BLOGGER_PHOTO_ID_5437522115029786274" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 200px; CURSOR: hand; HEIGHT: 150px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhKkNYxZlTFEg2zfCNtPan5VpsDfhvr9Y-lqs7-srKrHfZ9XPITJ_IPymmjnslhvvdrGLIRmZPU1FVtia_2ms9APPOpDk8jk3EOl1DwYDX_X5uGIWrHUKefIok8bBV6xtR4k4LXgPH710E/s200/DSC03732.JPG" border="0" /></a> Now, working from both sides, firmly pat the coil into a flattened elipse. You can see the section that we want in this image... this is the general shape of the cup handle that I want on a mug like the ones we have been making.<br /><br /><br /><br /><br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjrIuw_KuCb-Gqkj4i0uRh51YI3SeRwlqjYFdDU5OjDg2_KKxw2F5X2bKWE-dn8l0KrHqpMoux-dKYQNVXlZwm8Kz8YjrVV5-rKJyueWCrDTIAUD2p2CTenKwA83fp4XttPvj0M0ijdu2A/s1600-h/DSC03733.JPG"><img id="BLOGGER_PHOTO_ID_5437522121999810930" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 202px; CURSOR: hand; HEIGHT: 152px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjrIuw_KuCb-Gqkj4i0uRh51YI3SeRwlqjYFdDU5OjDg2_KKxw2F5X2bKWE-dn8l0KrHqpMoux-dKYQNVXlZwm8Kz8YjrVV5-rKJyueWCrDTIAUD2p2CTenKwA83fp4XttPvj0M0ijdu2A/s200/DSC03733.JPG" border="0" /></a> With the serrated rib, score deeply into an area about 1" x 1-3/4" just to the right of the vertical join. You don't want it sloppy wet - just scraped up a bit. If your cup, or any piece upon which that you wish to pull a handle, has begun to dry at the top and is changing color, do not attempt to pull a handle. You will have cracking! The cup will have already begun to shrink, and when the handle starts to shrink as it dries, it will pop right off. Be especially careful in summer....<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiWSmO1mJdweLBE9tQu3OgYS7aNEdWJysUiktDeeHblXJX3Ctxipfp8jIg2LcX2AK6j-KSYvCjRX3MneOB1DIumUU-2Yl83a62X_fq-jUqdNcG4PCv_XBEtEJP_NTkixoMA-NYOwRn3oqI/s1600-h/DSC03734.JPG"><img id="BLOGGER_PHOTO_ID_5437522129957765170" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 200px; CURSOR: hand; HEIGHT: 150px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiWSmO1mJdweLBE9tQu3OgYS7aNEdWJysUiktDeeHblXJX3Ctxipfp8jIg2LcX2AK6j-KSYvCjRX3MneOB1DIumUU-2Yl83a62X_fq-jUqdNcG4PCv_XBEtEJP_NTkixoMA-NYOwRn3oqI/s200/DSC03734.JPG" border="0" /></a>Take your handle blank in your left hand (sorry, Lefties, you'll have to reverse a lot of this) and working from the center out with short strokes, score the handle attachment plane. A nice bead of worked clay will extend over each edge if you do it right.I have just pushed the handles onto the cup bodies in the picture below. Handles WANT to stick to the cup! I can't emphasize enough how important it is to have both cup and handle at similar stages of drying is for this process to work right.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgL-atIAHTshO422gw8ynfGSw4Bjnw2L4Jd_ubTOy7-IP2LRIxY7YZ-qAY1VNb3o_mGMC7KmioS2hgznchtC61R8AP1enC8102ryX-bp2VfBEbKJOCFs-UHRk4dnukMmDKz8nCkTWv8-Mg/s1600-h/DSC03735.JPG"><img id="BLOGGER_PHOTO_ID_5437522135721722290" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 200px; CURSOR: hand; HEIGHT: 150px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgL-atIAHTshO422gw8ynfGSw4Bjnw2L4Jd_ubTOy7-IP2LRIxY7YZ-qAY1VNb3o_mGMC7KmioS2hgznchtC61R8AP1enC8102ryX-bp2VfBEbKJOCFs-UHRk4dnukMmDKz8nCkTWv8-Mg/s200/DSC03735.JPG" border="0" /></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhM8muxkKzvSwkK_B5E_9xsLJ1hy4yzA5xDRayJUAmxk-NRsZbvY8p7kaSWH6k13wGr6TVPD7BC9u2a6FiugdNMb6Rw9F1f3RD88CsUQ_WyxpMsVVnsH5XLLU8YLPXR5GQ0MGfNscjrI3I/s1600-h/DSC03736.JPG"></a> Use the tip of your finger to <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhM8muxkKzvSwkK_B5E_9xsLJ1hy4yzA5xDRayJUAmxk-NRsZbvY8p7kaSWH6k13wGr6TVPD7BC9u2a6FiugdNMb6Rw9F1f3RD88CsUQ_WyxpMsVVnsH5XLLU8YLPXR5GQ0MGfNscjrI3I/s1600-h/DSC03736.JPG"></a>smooth the join where the handle meets the cup.

I'm sure you could get them on the net.... I pick out a likely one and check it against the diameter of the cup, and then cut a clay bottom for my cylinder with it.<br /><br />Before I had the cutters, I had a small collection of round things that I used as templates; mostly jar lids and lids from plastic containers. You can easily size slab for a specific template diameter by measuring around the circular object with a tape measure. The measurement is usually about 1/4" longer than the slab needs to be. A little patience with the trial and error process will yield a nice fit, just be sure to jot down what slab size is required for a particular circular template.<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhqeCwfRz4LIwX1izlULN-Kii4U9FyBh63HSSzxktRs0xYtNmok0g3Kp4d8GX8ZLZc1robDF26mJ8Opj-jgco5FK90P0FS-buh92S3p6HPUbJ6byAGuFXnwWoF288EO9cnDtgzV3eIDhGw/s1600-h/Pick+a+Lid+Cutter.JPG"><img id="BLOGGER_PHOTO_ID_5437131440865102466" style="WIDTH: 160px; CURSOR: hand; HEIGHT: 131px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhqeCwfRz4LIwX1izlULN-Kii4U9FyBh63HSSzxktRs0xYtNmok0g3Kp4d8GX8ZLZc1robDF26mJ8Opj-jgco5FK90P0FS-buh92S3p6HPUbJ6byAGuFXnwWoF288EO9cnDtgzV3eIDhGw/s200/Pick+a+Lid+Cutter.JPG" border="0" /></a> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3_TLoxqya-vLZ7a7-ljkoVh4TsIDc1gc5O9vlQNt3vg3hGd6c97hWG3X1cCUPZlT8oXJ5Y-tUogRa8RjyA9_9-pQQTXq07GJCP94UUpxtKrXmoUORTV9K_tk7o2_uCfb1-ZUdtPRpchM/s1600-h/Check+Bottom+Size.JPG"><img id="BLOGGER_PHOTO_ID_5437131456937492578" style="WIDTH: 131px; CURSOR: hand; HEIGHT: 132px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3_TLoxqya-vLZ7a7-ljkoVh4TsIDc1gc5O9vlQNt3vg3hGd6c97hWG3X1cCUPZlT8oXJ5Y-tUogRa8RjyA9_9-pQQTXq07GJCP94UUpxtKrXmoUORTV9K_tk7o2_uCfb1-ZUdtPRpchM/s200/Check+Bottom+Size.JPG" border="0" /></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi41m9DHdMwyEbyQmuJMf_ZiTzllaTiURFU5Yz1ajtsXZfLw6JPnycFGzVzCUnRLcsv27K0ri7lGro8hzJwX96M6FyWoyjgHhjy9QeVPNmO8pgLWQHi5Gb5Rrx9Cz367x3MC1iarAaYyMk/s1600-h/Cut+the+Bottom.JPG"><img id="BLOGGER_PHOTO_ID_5437131459903780770" style="WIDTH: 141px; CURSOR: hand; HEIGHT: 132px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi41m9DHdMwyEbyQmuJMf_ZiTzllaTiURFU5Yz1ajtsXZfLw6JPnycFGzVzCUnRLcsv27K0ri7lGro8hzJwX96M6FyWoyjgHhjy9QeVPNmO8pgLWQHi5Gb5Rrx9Cz367x3MC1iarAaYyMk/s200/Cut+the+Bottom.JPG" border="0" /></a><br /><br />Now, moisten and score both the bottom of the cylinder and edges of the circular bottom with a serrated rib. It's good to have a close fit, but if the bottom is a bit large be sure that the cylinder is centered on it. After the bottom begins to adhere, flip the cylinder, which I guess is now a cup, over. You can gently move the cup around as needed to center, or adjust the edges. It will slide on the film of water for a few minutes after it is set on the bottom.<br /><br />I usually attach the bottom with the cup upside down. You can see the neatly fitting bottom ready to become part of the cup below. Just a little smoothing with the finger, and perhaps a careful sponging with a little piece of sponge is all that is needed to finish the bottom.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhDoxs30mhybC-qkY7PNEgYJfPbHvsd5P8spYqelgX4OKNufWU2k2bxQ0UDHQX9ZmOCHI-Hs7Do9GScBlDrWGXok_pAPL1V_xT68GZL1lqoMwZ41ldNd4j0wZ_uJzVauTtogMwEBwOlbuw/s1600-h/DSC03709.JPG"><img id="BLOGGER_PHOTO_ID_5437217548984701746" style="WIDTH: 127px; CURSOR: hand; HEIGHT: 113px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhDoxs30mhybC-qkY7PNEgYJfPbHvsd5P8spYqelgX4OKNufWU2k2bxQ0UDHQX9ZmOCHI-Hs7Do9GScBlDrWGXok_pAPL1V_xT68GZL1lqoMwZ41ldNd4j0wZ_uJzVauTtogMwEBwOlbuw/s200/DSC03709.JPG" border="0" /></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj264wXswpQe3tZbi43ZhhU6RBikn3ILFg3ttzIyf12P7oS5TZMUphzbmrBL4i7Gn_kzvOuCO8gdzb1l3gtPtEt3WkOLHbYEZrHoapM3xWFudZ9nvv0bGs-vxpeihnO0eeqKzDiYZE6fd4/s1600-h/DSC03710.JPG"></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkT911axaF38_Frq8YFVHRSIRkT_5jLusL7kFkS3mTzIWCqFuwDhIfJsbGHcVL4f6k7Cj7Ye1ToSds22ldIXIkabjHsGkY3Fkst7dBuR5E-mmhUyaSQj2u5NvP4e-If5cHV3g_HHsiFQQ/s1600-h/Score+the+Circle.JPG"><img id="BLOGGER_PHOTO_ID_5437217575094354642" style="WIDTH: 119px; CURSOR: hand; HEIGHT: 113px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkT911axaF38_Frq8YFVHRSIRkT_5jLusL7kFkS3mTzIWCqFuwDhIfJsbGHcVL4f6k7Cj7Ye1ToSds22ldIXIkabjHsGkY3Fkst7dBuR5E-mmhUyaSQj2u5NvP4e-If5cHV3g_HHsiFQQ/s200/Score+the+Circle.JPG" border="0" /></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgZOHykuoEwe0TKK32CMpKRYWxLhMa-fZMVRcnoMnHdR6uDKznAyv_2JwDdBzMN3ZaXZST_V4-rA3oaeiCC1tbsAfXnasSdZSeknAQI32CnHykL9GcbKJW1Of6PyMZSlVZMCcXv0ZRAdCc/s1600-h/DSC03711.JPG"><img id="BLOGGER_PHOTO_ID_5437219966231733474" style="WIDTH: 141px; CURSOR: hand; HEIGHT: 114px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgZOHykuoEwe0TKK32CMpKRYWxLhMa-fZMVRcnoMnHdR6uDKznAyv_2JwDdBzMN3ZaXZST_V4-rA3oaeiCC1tbsAfXnasSdZSeknAQI32CnHykL9GcbKJW1Of6PyMZSlVZMCcXv0ZRAdCc/s200/DSC03711.JPG" border="0" /></a><br /><br /><br />Just a swipe with the finger<br />is enough to seal the seam.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiNvCyZJbxHs8y5uxEz7tNN6MfJtfqb8IRR3AAjOO8PP_lCf1FJGqQEXaRNdZfj12aId7GZw5jpa_W-BLibmTNAA7DIqMSNzYcJTvf_eQEay23uVrCQgC13tf32AgnU7GAuwQfcY4DJEuQ/s1600-h/Seal+Bottom+with+Finger.JPG"><img id="BLOGGER_PHOTO_ID_5437221265670202082" style="WIDTH: 200px; CURSOR: hand; HEIGHT: 150px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiNvCyZJbxHs8y5uxEz7tNN6MfJtfqb8IRR3AAjOO8PP_lCf1FJGqQEXaRNdZfj12aId7GZw5jpa_W-BLibmTNAA7DIqMSNzYcJTvf_eQEay23uVrCQgC13tf32AgnU7GAuwQfcY4DJEuQ/s200/Seal+Bottom+with+Finger.JPG" border="0" /></a><br /><br /><br />A tool can be used to firm the<br />vertical join.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgPGlgxmO80VnykQS5PwZ8zzWAZElurwvn5aHGQFbWZIZunWNnh1wO5sMUCokBlSduDq5FnoR4bvAxISng4fO0GPZ8q6Q47XbXh6EGEEo-0XAwKqloNCn8HzGFffI1e4iL40L5LRfVzFSE/s1600-h/Seal+the+Seam.JPG"><img id="BLOGGER_PHOTO_ID_5437221274304095586" style="WIDTH: 200px; CURSOR: hand; HEIGHT: 190px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgPGlgxmO80VnykQS5PwZ8zzWAZElurwvn5aHGQFbWZIZunWNnh1wO5sMUCokBlSduDq5FnoR4bvAxISng4fO0GPZ8q6Q47XbXh6EGEEo-0XAwKqloNCn8HzGFffI1e4iL40L5LRfVzFSE/s200/Seal+the+Seam.JPG" border="0" /></a><br /><br />Now, the finished cup can be set aside to stiffen in preparation for pulling a handle. If the top rim is firm and level, the cup can be turned upside down. If it is soft, cover the cup with plastic so the mug can firm up slowly.

I don't wrap the blank around the mailing tube, I drape it over the tube in a horizontal position. I support the tube with my left hand, and with my right hand press the slab to conform to the curve of the tube. It's important that each of the sides is pressed into the form of the tube.<br /><br />When you have curved the entire piece, set the tube and curved blank down on what will be the bottom edge of the cup. The top will have a nice rounded rim, while the bottom will still have square edges. Slip the tube out of the cylinder and set it aside. Position the left side of the cup blank, which has scoring on its' outer edge under the right side of the cup blank, which has scoring on its' inner surface. The cylinder should be sitting level, and the tops of each side should be level, or close to it. Gently press them together, and let the clay surfaces adhere for a few minutes before smoothing the join further. Just your finger will do at this point, a tool can be used to finish the join more completely when the piece is at a dryer state. The tube can be reinserted into the cylinder and used to resist pressure from your fingers, or the brayer. Be gentle and don't deform the join - the clay has a will to stick to itself....<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgZnOEow8Akvph1IUpChmMb9KwqnTdIJ5GkeFGH3sieIvpdDuTWXJCoLSFIvpl4dQlLsDxVdIo3tbpoXImrp97Z5gJ1hWr5_invj0XjxBVdhNRFBZDUGmt9WgAouyHDc4VlZ_3ZtNPIEAI/s1600-h/Shaping+with+Tube.JPG"><img id="BLOGGER_PHOTO_ID_5437107691446526866" style="WIDTH: 200px; CURSOR: hand; HEIGHT: 162px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgZnOEow8Akvph1IUpChmMb9KwqnTdIJ5GkeFGH3sieIvpdDuTWXJCoLSFIvpl4dQlLsDxVdIo3tbpoXImrp97Z5gJ1hWr5_invj0XjxBVdhNRFBZDUGmt9WgAouyHDc4VlZ_3ZtNPIEAI/s200/Shaping+with+Tube.JPG" border="0" /></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiy-t9B2F6v8yshb8JfWHfX96Fak4cl3iDhgpilr8E0ZyICVMYlSDETAbBoW3hl-c2QugbW-j8pGVK6rHYBC01-B4ppbjVjtylylUZ52LE3H7Pxc0Fr5Rs1OI3HVnTPaKFAxwHerm8z-v0/s1600-h/Cup+and+Paper+Tube.JPG"><img id="BLOGGER_PHOTO_ID_5437107701709885538" style="WIDTH: 178px; CURSOR: hand; HEIGHT: 200px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiy-t9B2F6v8yshb8JfWHfX96Fak4cl3iDhgpilr8E0ZyICVMYlSDETAbBoW3hl-c2QugbW-j8pGVK6rHYBC01-B4ppbjVjtylylUZ52LE3H7Pxc0Fr5Rs1OI3HVnTPaKFAxwHerm8z-v0/s200/Cup+and+Paper+Tube.JPG" border="0" /></a><br /><br /><br /><br /><div></div>Ginger Steelehttp://www.blogger.com/profile/02859169181773574347noreply@blogger.com0tag:blogger.com,1999:blog-2992770042811485395.post-84810872272361961382010-02-11T13:39:00.001-08:002010-02-11T13:51:07.207-08:00Step 4 - Preparing the Edges of the Slab Blank<div> </div><div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi26sjNH9MTMueXdTbJXJvZrx786vcysWyRN4FnFrVKYuH-NhJdDYc7uKuEhjEjz7YxL9xMvbhAz-KQWWshFFDN62_1kQmvGQN1rkoPE6krhObnXfvlj7tAUP44ymKxLujdqKR3_HdsGa8/s1600-h/Score+Left+Edge+2.JPG"><img id="BLOGGER_PHOTO_ID_5437104214853510658" style="FLOAT: right; MARGIN: 0px 0px 10px 10px; WIDTH: 159px; CURSOR: hand; HEIGHT: 200px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi26sjNH9MTMueXdTbJXJvZrx786vcysWyRN4FnFrVKYuH-NhJdDYc7uKuEhjEjz7YxL9xMvbhAz-KQWWshFFDN62_1kQmvGQN1rkoPE6krhObnXfvlj7tAUP44ymKxLujdqKR3_HdsGa8/s200/Score+Left+Edge+2.JPG" border="0" /></a></div><div>Using a serrated rib dipped in just enough water so it can be seen wetting the surface, carefully score the left edge of your cup blank.

The first image shows a nice brass roller from a bookbinding shop applying a row of dots. I make many of my texture tools from thrown rollers or leather hard blocks of clay.<br />I generally apply horizontal bands of decoration, but there are probably a zillion other possibilities that I will never think of... you can also leave your cup unadorned, or incise or carve imagery at a later stage of dryness.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgZoR8kGvw28Ew1Zsf3ygUhi9cAYdxoi3oL3-EyuojfiAn1X9KerJLjIA-GVrwBQOQkYQk4XkSqCwR7PiA2OmNtBxxCneRA6EVV7ZSOi8LmOe-0814CHXwca1NJWd8daqqOEjVW59d6OdE/s1600-h/Texture+Tools+and+Cup+Blank.JPG"><img id="BLOGGER_PHOTO_ID_5436775453943840354" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 200px; CURSOR: hand; HEIGHT: 142px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgZoR8kGvw28Ew1Zsf3ygUhi9cAYdxoi3oL3-EyuojfiAn1X9KerJLjIA-GVrwBQOQkYQk4XkSqCwR7PiA2OmNtBxxCneRA6EVV7ZSOi8LmOe-0814CHXwca1NJWd8daqqOEjVW59d6OdE/s200/Texture+Tools+and+Cup+Blank.JPG" border="0" /></a> Each time texture is applied to the blank, clay is moved. If you apply horizontal bands of pattern, the clay will stretch in the direction that your roller is pushing it. Generally the clay blank will be stretched at least an inch during texturing, and will need to be recut before it is made into a cylinder. It's good to practice on scrap clay with your texture tools so you create the right pressure when you do decorate your blank. Pressing too hard may cause the clay to weaken, or to be distorted when it is formed.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhrNMPgdOMUfeJGuKkOmu6Be74eMDmRwUCg8DzIol9U4m6jkkQRNUT2ZWCXMNPetklOG684r2gdtyta-RUQhyphenhyphenRb0PWLNbM9YwAeFVTxMWdOpQq90dDcQG80_b8il7KlV4aBhv_qVnbh9YI/s1600-h/Textured+Slabs.JPG"><img id="BLOGGER_PHOTO_ID_5436775462732654338" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 200px; CURSOR: hand; HEIGHT: 154px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhrNMPgdOMUfeJGuKkOmu6Be74eMDmRwUCg8DzIol9U4m6jkkQRNUT2ZWCXMNPetklOG684r2gdtyta-RUQhyphenhyphenRb0PWLNbM9YwAeFVTxMWdOpQq90dDcQG80_b8il7KlV4aBhv_qVnbh9YI/s200/Textured+Slabs.JPG" border="0" /></a>Here are the two cup blanks ready to be formed into cups. Usually I will texture about 8 cup blanks at a time, so the first will be stiffening up while the last are being textured. I like the clay to be firm, but still flexible and able to stick to itself when it is scratched up with a serrated rib. A pulled handle will be added, usually the following day, so the mug must be kept moist enough for the handle to attach easily.Ginger Steelehttp://www.blogger.com/profile/02859169181773574347noreply@blogger.com1tag:blogger.com,1999:blog-2992770042811485395.post-6948572798273328942010-02-10T16:09:00.001-08:002010-02-11T13:36:33.258-08:00Step 2 - Pressing the Edges of the Cup Blank<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjEqkkXGlVRvcn3iw1-xh42Mf2dzJAdR-b_wTzQFi4q8yfA-0-2zRr7wbTfP5I9VPgWMBwunqGMRGst3ly-6KB_KO36SGwdHxiVOnaVsL9rKIveuxk8Vv9eHofqHbbcQOSS8uwVxkf6H80/s1600-h/DSC03687.JPG"><img id="BLOGGER_PHOTO_ID_5436771688280531474" style="FLOAT: right; MARGIN: 0px 0px 10px 10px; WIDTH: 200px; CURSOR: hand; HEIGHT: 150px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjEqkkXGlVRvcn3iw1-xh42Mf2dzJAdR-b_wTzQFi4q8yfA-0-2zRr7wbTfP5I9VPgWMBwunqGMRGst3ly-6KB_KO36SGwdHxiVOnaVsL9rKIveuxk8Vv9eHofqHbbcQOSS8uwVxkf6H80/s200/DSC03687.JPG" border="0" /></a> Now, use a small brayer to gently press the right and top edges of your 5" x 10" clay cup blanks. Now, carefully turn your blanks over and press the reverse sides of the top and right edges. This will give the top of your mug a refined look - and a rim as nice as that of a thrown cup. If you press too hard, you will create a sharp or unattractive edge. Practice with the brayer on bits of scrap until you achieve a nice, rounded look. Many handbuilt cups have a crude or ragged rim that detracts from the visual appeal of the cup.<br /><br />This tool is not actually a proper brayer for printmaking use, but is a wall-paper seam sealer from the hardware store. They cost about $3, and are available made from wood or plastic - each works equally well.Ginger Steelehttp://www.blogger.com/profile/02859169181773574347noreply@blogger.com0tag:blogger.com,1999:blog-2992770042811485395.post-32947451967227299822010-02-10T16:01:00.000-08:002010-02-11T13:37:21.991-08:00Step 1 - Measuring the Cup Blanks<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjQCP3PzYUZc2MCcnhsiPpzmapILCY7K4rGcuU60h2AbCjesSCmRKm2sDcElAzuSQnrsTFl6mf62kvkKSvFB_sUss9E2PZOME0UjeLtrp6L5sVfE-HKPsuo33ReNgy0LJLv7-W3GVIy8DE/s1600-h/Slab+and+Quilt+Rule.JPG"><img id="BLOGGER_PHOTO_ID_5436769522947141026" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 320px; CURSOR: hand; HEIGHT: 214px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjQCP3PzYUZc2MCcnhsiPpzmapILCY7K4rGcuU60h2AbCjesSCmRKm2sDcElAzuSQnrsTFl6mf62kvkKSvFB_sUss9E2PZOME0UjeLtrp6L5sVfE-HKPsuo33ReNgy0LJLv7-W3GVIy8DE/s320/Slab+and+Quilt+Rule.JPG" border="0" /></a><br /><div></div><br />Here's a slab that is about 12 x 12 inches.
