Cold Characteristics

Opaque.

Working Notes

Torch: Lighter color and greater opacity than in sheet glass form. Keep it a bright yellow by working with a neutral to oxidizing flame atmosphere. Can turn gray in reduction.

Kiln: Lighter color and greater opacity than in sheet glass form.

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.
