No, sorry. Plaster of Paris expands and the plaster will stick to your molds and is impossible to remove. It will also remove some of the fine detailing of your mold. An alternative is to put the plaster on one of your finished pieces, half at a time to get a mold of the piece. This will give you a new mold of the piece without destroying your original mold.

Clay can be molded by hand or by using a potters wheel to shape it. There are many techniques for shaping clay both by hand and machine. One of the common ways to mold clay is by liquefying the clay with water to make slip. The slip is then poured into molds made of plaster. The plaster absorbs the water from the clay leaving a clay wall behind in the mold in the shape of the mold. The mold is then disassembled and the resulting form, known as greenware, is slowly dried and then fired.

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.
