Casting WED clay, cracking
in Sculpture
I recently finished a full-size head and shoulders sculpture out of WED clay. I kept it hydrated while working on it, but once I was happy with it I figured I would let it dry, then make a silicone mold from the dry piece.
Unfortunately I think I am going about this wrong, since the clay has started to crack now that it is drying. When is the appropriate time to make a mold of a WED clay sculpture? Should I have been making a mold while it was still wet? Is it possible to make a mold of a dry WED model? Is my sculpture going to fall apart?
Any help or advice would be much appreciated. Just to be clear, I am aware of how to keep the clay moist while working on it, I thought that once it was finished it would be safe to let it dry.
The two photos are from a couple days of drying.
