Interior Supports?

11 October 2010 - 09:26 PM

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.
