After adding a layer of tenmoku glaze over & into the stamped textures, I gently wipe away the “top layer” to reveal the glaze inlaid in the impressions. It also really helps “pop” the dab of colored flashing slip in the middle of each stamp… details matter!

Getting ready for tonight’s SODA-FIRING WORKSHOP at Lillstreet. My students will be bringing their own bisque to glaze, wad & load tonight. I am glazing up some of my own work as “kiln filler” in case they don’t have enough work to fill the kiln. It’s always tough to estimate the amount of work going into the kiln load. Some of my workshop students have never soda-fired or even been to Lillstreet before… so it will be an interesting mix tonight, and I just want to have a back-up plan ready in case they don’t bring enough work!!!

So Ive been working on some more of my “handbuilt-wheeltrown-combo” mugs. The bottoms are wheelthrown, the sides handbuilt, and then trimmed & refined on the wheel again! One of my favorite “tricks” for making fun textured mugs!

I start by making some textured slabs of clay. Sometimes with my own stamps, texture mats, or carved rolling pins… like this great one from STODOLA!!! They make tons of different rolling pin textures… including custom designs if you need that. Check ’em out at www.stodola.org.

After pressing in a texture, I cut them into straight-sided rectangles… long enough to be the circumference around the base of the cup.

I throw little “bases” on the wheel… just a small little disc wheelthrown on a plastic bat. I do NOT wire them off as I will be putting them back on the wheel to continue to the process and I want them to stay centered.

I start assembling them by wrapping the slab around the base – scoring & slipping along the way. One of the benefits of this technique is that the weight of the slab is supported by resting on the plastic bat. The extra part below the wheelthrown bottom will be trimmed off later. But it makes a great support system at this point.

Where the slab overlaps, I cut it on an angle and then connect that seam… trying to blend it together as best I can without ruining the pattern. A good “secure” seam is pretty important here.

After attaching the sides, you can spin them on the wheel and press outwards from the inside to give the cup a little curve & volume. I also give the rim a little extra attention to keep it round & smooth… like a wheelthrown cup.

I let the cylinders set-up overnight before trimming… under plastic so they dry slowly to leatherhard. At this point, they can be wired off the plastic bat.

I start by cutting off the excess slab that is “under” where the slab attaches to the wheelthrown disc with a sharp blade. Confusing a bit… as it is now “above” the connection point as the cup has been flipped for trimming.

Then I start trimming the bottom as though it were a “normal” wheelthrown cup. The Giffin Grip helps hold everything in place and centers things quickly! And my DiamondCore Trimming Tools work great for trimming a clan, crisp footring. I make sure to trim all the way into the textured slab so that it blends together and looks seamless.

Once trimmed, I let them sit under plastic while I pull some handles for them. Cups are cups… but a mug needs a handle!!!

So when the handles stiffen-up a bit, I start attaching them to the sides… usually where the seam is as a little “creative camouflage.”

I let the mugs sit under plastic overnight again so that they stiffen-up to leatherhard and the moisture levels balance out. Since these are going to be soda-fired, I decided to dip them in thin colored flashing slips. I held them by the footring and carefully submerged them into the slip to only cover the textured slab sides. I left the curved wheelthrown bottoms as raw clay. I think that the difference will look cool after soda-firing! As the slip was dripping wet after dipping, I propped them up on kiln posts so the dripping would stop before flipping them back over. I didn’t want big drippy runs going down the sides.

So now they’re drying and getting ready for a bisque firing. Once fired, I will add a liner glaze and maybe some other colored glaze accents. After soda-firing, the textures should pop nicely and the flashing slips will help accentuate the pattern.

Finger crossed.

A bisque it, a basket…
a kiln full of soon to be bisqued baskets!

And a few other things…
four & a half layers of mugs, flower pots & more fun!

Here’s my class demo bowl after wiping away the background from the shellac pattern. If you look close, you can see the raised edges along the sides of the pattern. When the piece gets bisque fired, the shellac will burn away and “reveal” the raised pattern that has a orange flashing slip top surface. My plan is to do a tenmoku liner glaze on the inside of the bowl and then soda-fire it “raw” on the outside to see what happens. I’m kinda excited… you know I love a good challenge… and it’s always fun to see where it takes us!

After doing my first class demo with the water etching technique, I decided to go one step further with another demo piece. My first bowl was more random with multiple patterns kinda like a “sampler” just on the B-clay surface. This time I first covered the exterior with an orange flashing slip, then painted on this swirly pattern with shellac. My hope is that when I “wash away” the background, the pattern will be raised and the orange slip will POP more after soda firing… and the raised edges will catch some soda too!!!

Funny story…
While I was making these crackled slip vases, one of them “slumped down” a little as I might have bulged it out a bit too far. I let it sit on my work table while I made more… mocking me… always looking at it thinking that the shape was bad. Questioning if I should just squish it up and do it again. But then I remembered one of my students Dan who always tries to flip-over his slumping pots to see if gravity will “un-slump” them. I figured what do I have to lose?! It was still firmly attached to the plastic bat, so I flipped it, tapped it a few times and then hung it upside down overnight in a bucket with plastic over it. The next day… voila’… the slumped area had “stretched” back out and the curve was all better… and perfect for trimming!!!

Thanks Dan for the unwitting motivation! HA!!!

Celebrating another MUGSHOT MONDAY
by making more mugs… and adding handles!

I’ve had this discussion before with my students…
“Can a mug be a mug without a handle?”

They seem to think you can as an “avoidance” to making handles…
I of course think not. I love making mugs. I love making handles!
They go together… by definition I believe.

After teaching class this morning, I pulled some long handles and let them hang off the edge of my wedging table to stiffen up. For mugs I like to flip them to set the curve of the mug handles… but for these “basket” handles I wanted them a bit thicker, longer & straighter!

Staying warm, staying inside… making more bowls in the studio. Can’t wait for these to stiffen up a bit so I can stamp them and move them along in the process… let the transformation begin… soon to be “something to behold”!!!
