Tomato Red Opal Frit (024)

Sulfur glass that reacts to the copper glasses. May react to silver. Tomato Red is a striking glass. Striking glasses are those which, when in their cold state, do not display their target color. They must be fired and held at 1225 degrees for a period of time before reaching that target color. Color opalizes upon firing, becoming more consistent. Color may dapple with excessive heatwork.

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.
