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.
