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

Opaque.

Working Notes

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.

Torch: Depending on the heatwork of the glass, as indicated by color when it is put into an annealing kiln, a range of colors may be achieved. If this glass is put into an annealing kiln with a deep brown hue, a target Cinnabar color will result in the finished piece. If it is very light beige, as opposed to deep brown, and the desired result is Cinnabar, gradually cool and reheat the glass without bringing it to a soft state. Look for it to turn deep brown and then put it into an annealing kiln.

Kiln: Lighter color and greater opacity than in sheet glass form. Rod color is close to Burnt Orange Opalescent (000329) after a full fuse firing.
