A very dark brown midrange stoneware that fires near black and looks rich and sophisticated unglazed. It is formulated with lower manganese, is less prone to bloating than older dark clays, and fires to zero porosity for strong, durable ware. Great for marbling with lighter clays. The 50 lb dry bag is powdered clay you mix with water yourself.
- Firing range: Cone 5
- Wet color: Red brown
- Fired color: Very dark gray, black under glaze
- Texture: Slightly smooth, under 5% grog
- Shrinkage: About 10.1% at cone 5
- Dark clay tips: Leave room in the kiln for off gassing, use a slow bisque and a faster glaze firing. Contains manganese and a little cobalt, so wash your hands after use
- Sizes: 12 lb Cube, 25 lb Block, 50 lb Dry Bag
Photos show the clay at greenware, bisque, and glaze fired stages, plus glaze tests, so you can see how it fires.
Good to know: Moist clay ships sealed and ready to use. Keep it wrapped tight between sessions so it stays workable. Always test new clay and glaze combinations on a tile before a full kiln load.
