Contains sulfur and may react to copper bearing glasses. Orange 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. This style is not suitable for kilncasting because it can opalize and/or become incompatible when held at high temperatures for an extended period. It may also opalize and/or become incompatible in instances where processes exceed the parameters of the test for compatibility. Testing recommended when heatwork exceeds these parameters. Slight reactive potential to lead bearing glass. Slight reactive potential to lead bearing glass. Sheet sizes are: 1/2 Sheet - 20" x 17 1/2" 1/4 Sheet - 10" x 17 1/2" 10" x 10" 5" x 10" 5" x 10"s are perfect for testing colors before you commit to buying a larger piece, or if you just need a small piece. **Please note, 5" x 10" pieces may vary in size.** REACTION CHART Reaction Chart: Download PDF Bullseye Price Code C
