Re:[teacherartexchange] cracked clay

2 reasons: you may be leaving water in the bottom of the bowl when you're finished--
it causes cracks because the bottom stays wet when the rest is dried and shrunken.
Another thing that would help would be to open the bottom of the bowl, then wring the
water out of your sponge and press the bottom of the pot with it. It will compress the
molecules just as you compress the sides when you lift. Sid

I'm not sure, but we always let our clay pieces dry on
a piece of newsprint so as the piece shrunk the paper
would move with the clay to avoid cracks.
