Contains: Selenium, Sulfur

May React With: Copper, Lead, Silver

Cold Characteristics: Variation in color density.

Working Notes: Color matures to red and becomes more consistent upon firing. This style is not suitable for kilncasting because it can become incompatible when held at high temperatures for an extended period. It may also become incompatible in instances where processes exceed the parameters of the test for compatibility. Testing recommended when heatwork exceeds these parameters.
