Contains Lead May React With Selenium, Sulfur
Varies from lighter to darker; sometimes with lighter dappling in single-rolled sheets.
Colour usually deepens on firing. Possible dark interface reaction with selenium and/or sulfur glasses (001122, 001125, 000124, 000125, 001137, 001437, 000137). Less viscous (softer) than most other glasses.
Some gold-bearing striking glasses, like this one, need to be fired slowly during the initial stages of the firing cycle. If fired too fast, they may not strike at all, or they may strike but appear spotty and have a blue-brown cast, as opposed to the desired target color.
This standard full-fuse schedule effectively strikes these glasses:
For colour-sensitive projects, we recommend testing the cycle you plan to use by fusing a small sample of a similar setup in the same kiln as the project to best predict final colour results.
