Since the mold absorbs water, if you want to get a good pour don't let the mold too wet. One excellent indication is how heavy it is because the thing is waterlogged. Sitting it empty in your kiln room is one way to get it dry. DO NOT cook the thing! But a hot dry environment is the best way to keep your molds useable. I wouldn't pour in the same mold more than three times before letting it dry up some. If you pour too much at a time, you lose the fine detail because the plaster deteriorated. If it's a very popular mold, try getting two.

Why does ceramic slip stick to plaster mold?
The plaster mold is very, very dry. When you pour, the clay slip is mostly water and the plaster mold sucks up the moisture quickly, creating a coating inside the mold. It's like pouring gravy onto a sponge...the water is absorbed, but the solids stay on top of the sponge if you leave it long enough. It's the same way with a plaster mold..it's a sponge. That's the reason you watch the pour opening and pour out the excess when it is the thickness you need. The plaster will continue to absorb until the clay pulls away from the mold naturally, yet it is still green.

What are the materials used in relief painting?
I pour liquid paper mache into a plaster mold to cast a model which I then paint in either acrylic or oil paint. I adhere the cast, painted model to a wooden board upon which a scene in acrylic or oil paint has been painted. The cast model blends with the background scene and seems to emerge from the background. I sometimes enclose the finished work in a shadowbox. To see examples of some relief paintings I have created go to www.cameoqueen.com/.

What is lost cast waxing?
Lost wax casting. You make something out of wax, jewelry or something similar and attach one or more strips that will act like tubes when the wax is melted out of the mold. You put the piece in a metal container of the right size and pour plaster around it. After the plaster sets, you heat it so that the wax will run out. After this, you melt metal, gold or silver and pour it in the mold or there is a centrifugal caster that forces the molten metal into the mold and gives a better casting. With the mold hot from melting the wax out and the hot metal, you put it in water and the plaster blow off of the piece.
