in this random rambling thread we post random pictures

Are these then fired? I would be afraid of them exploding. Or are they used for casting?
Will they become bronzes? I thought they used wax for that.
If it isn't too much trouble, could you give me a quick explanation ?

Normally when the clay is finished you'd make a mold. In the old days it was a hard plaster piece mold (multiple pieces that key together). Now it is more likely a flexible silicone rubber mold, and then a hard shell over the mold to keep it rigid. That type of mold can bend around and under to get into undercuts, whereas with the old piece mold you'd need complex pieces to do that.

What is done with the mold depends on what material you are casting in. For bronze, you'd pull a wax cast; otherwise you might cast it in plaster or resin, with that being a final material.

I'm not sure if he is using water clay (which drys and cracks) or oil clay (plasticine) which remains workable for years. With some types of water clay, you can hollow it out and then fire it, making a terra cotta final piece. You could also mold multiple terra cotta pieces from a mold.

There are other options too, these are just the most common.
