Stamping and casting: objects shaped using ceramic molds
Clay stamping involves filling a ceramic mold, pressing the clay with your thumbs to form the shape of the mold. Once the mold is filled, a roughing tool is used to smooth the edges.
Similar to stamping, casting clay requires a plaster mold. However, the ceramist does not press a solid paste but fills his mold with "casting slip" (a liquid clay composed of water and ceramic paste).
