Contains sulfur and may react to copper bearing glasses. Slight reactive potential to lead bearing glass. Yellow 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 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. 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.** This glass is available in Pre-Cut Circles!
