How do I decorate my ceramics?

Terra Sigillata; Description

Terra Sigillata (or earth seal) is a slip containing very fine particles. It is created by a process of separation. We grind, using a ball mill, specially selected clays and water until the particles are extremely small. Deflocculant is added and the mixture is allowed to settle for twenty-four to forty-eight hours. The fluid left on top after settling is terra sigillata. Longer settling will yield a finer, higher quality product. After application, simple polishing with your hands or a soft cloth will shine terra sigillata to a high gloss. This smooth surface is ideal for decoration especially with smoke firing and other primitive techniques. After firing you will have a smooth, weather resistant coating much like a glaze.
