A casting slip may take the form of any clay body where some will be more challenging than others. Casting slip will fall into the same firing ranges as moist pugged clays; Low-Fire, Mid-Range, and High-Fire. The majority of slip casting falls into the Low-Fire category, which is an earthenware-based talc body that offers a bright, white surface for your colorful and bright Low-Fire glazes. Mid-Range bodies fall into 2 categories: Stoneware and Porcelain. Stoneware slip (like its moist clay counterpart) is very plastic which can pose a few challenges to a slip cast body but brings a more durable product. Porcelain bodies are less plastic, easier to cast, but can pose more challenges in the firing process. You will need to assess your needs for your body and acquire the skills required to control, cast, and fire the slip body you choose.
