Good quality plaster - an essential part of mold making. I usually use Plaster of Paris or pottery plaster that you can get in your local ceramics store. Don’t use construction plaster, which is a building material and is not suitable for delicate work with porcelain.
Plasticine - non-hardening modeling compound. Since plaster molds are usually two-part or multiple-part molds, you need plasticine for covering a section of the prototype where you don’t want the plaster to get in.
Mold box - it’s easy to make one yourself from wood boards or some cardboard. I'll show you how to do one in the next lesson.
