{"product_id":"eclipse-black-stoneware-clay-cone-5","title":"Eclipse Black Stoneware Clay, Cone 5","description":"\u003cp\u003eA 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiring range:\u003c\/strong\u003e Cone 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet color:\u003c\/strong\u003e Red brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFired color:\u003c\/strong\u003e Very dark gray, black under glaze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTexture:\u003c\/strong\u003e Slightly smooth, under 5% grog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShrinkage:\u003c\/strong\u003e About 10.1% at cone 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDark clay tips:\u003c\/strong\u003e Leave room in the kiln for off gassing, use a slow bisque and a faster glaze firing.
