Frequently Asked Questions (FAQs)

1. How do you use clay in plaster molds?

A round hump mold can be made out of clay on the potters wheel. Just center a lump of clay, use a rib or trimming tool if desired to alter and smooth the shape. Then plaster can be poured around this to create a slump mold. Once you have a slump mold, you can then pour plaster into it to make a hump mold.

2. Can you make a plaster mold from clay?

Pop some 'keys', little indentations, in the plasticine around the surface of your object with the end of a paintbrush so that you can create a 2-part interlocking mould. Vaseline up your clay and your object VERY THOROUGHLY. Plaster will stick to any unlubricated surface (except the plasticine of course).
