A mottled charcoal gray that looks excellent on dinnerware, Sorcerer's Stone is a consistent favorite at the Coyote studio. Depending on the clay it can vary from almost black to light gray, sometimes even breaking blue or brown on texture. Fantasy Glazes can vary dramatically in appearance depending on the clay body used, the thickness of application, and in some cases, the firing. They can be runny, so it's important to test carefully. Test all foodware to determine food safety. Visit our safety page for more inf ormation.
