    Interior Supports?

    Thanks; I'd be interested in seeing that. My studio, despite being in NOLA, dries my clay out quickly, so I'm constantly spraying slabs and pieces. I've got the parts for the current piece wrapped in 5 plastic bags, with damp cloth on that, and it's still iffy. It makes smaller pieces tempting.

    Interior Supports?

    Thanks, all. Anthony, I'm using Laguna c.6 porcelain, but plan to only fire to cone 5 (sag issue). I thought about a tube form, so your advice helps solidify that idea for me. I do know I'll need to be extra careful at joins to really smooth. Part of my brain still wants to push it and see if I can do it all hollow. I'm up to about 30 lbs. currently, so it will ultimately be around 50-60 lbs. Marcia, I think you're right, plus I started at the feet (tiny area where the weight concentrated). My second attempt I now have the torso set and will start on the extremities in the next few days. Christine and Riorose, I'd forgotten about the internal removal forms; thanks for reminding me. I had a teacher using Vermiculite in panty hose, which could be poured out after the shape had set up enough - d'oh! Sometimes I fear my brain is more interested in mirroring that of Homer Simpson instead of retaining useful information. All this is quite helpful, and I'll be utilizing your suggestions. Thanks again.
  3. I have begun, again, a sculpture - a hollow figure which will ultimately be 3 1/2 feet tall, a standing woman. I'm using 1/2" slabs. I have the torso, and due to kiln height constraints, planned to cut it into two pieces. Today, due to weight causing the bottom to split and crack, I went ahead and cut it into the two pieces, which are currently resting on foam. I still need to add legs, head and arms. I'm thinking I do need to add some internal supports, but then I've seen pieces without any. These are usually columnar. I'm concerned not only due to the weight of the remaining parts, but also sagging in the kiln. How much do I need to add? Just half circles, or braces from one side to another? My largest piece before was a bit over a foot, though she sagged on her poor bony legs, despite the "quilt" she was holding. I do plan to fire the leg section upside down. Anybody had to deal with this, and did so successfully? I am grateful for any advice and suggestions.
