Working Notes –

This glass can be unstable when subjected to extended
heatwork (pattern bars, pot melts, boiled effect,
kilncasting, etc.). Firing above 1500°F (815°C) for more
than 15 minutes or firing slowly between 1250°F (677°C)
and 1500°F (815°C) may result in an unstable glass. More
susceptible to contaminants that seed devitrification than
other glasses in the Bullseye line.

Cap with clear or plan to treat the surface (sandblast,
coldwork, or apply clear powder and refire) after firing. No
color shift upon firing. A dark interface reaction is possible
with sulfur-bearing glasses (001137, 000137). Dense White
Powder (000313-0008F) is recommended for surface use
only. It may crackle when used between sheet glass layers.
