Cold Characteristics

Color variations common from pastel to warm, vibrant yellow.

Working Notes

Lighter coloration matures and becomes consistent to target 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.

Cold Characteristics

A warmer version of 000120-0576, Canary Yellow. Opaque.

Working Notes

Torch: This dense opalescent stays true to color except when used in the smallest amounts. Keep it bright yellow by working with a neutral-to-oxidizing flame atmosphere. Can turn gray in reduction. We advise labeling all striking glasses.

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