Gold Purple contains lead and is a striking glass. Color usually deepens on firing. Possible dark interface reaction with selenium and/or sulfur glasses (000137, 001122, 001125, 000124, 000125, 001137, 001437). Less viscous (softer) than most other glasses. Some gold-bearing striking glasses, like this one, should be fired with a 2 hour hold at 1225°F during the initial stages of the firing cycle. If fired without this hold, 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 full-fuse schedule effectively strikes these glasses: Rate Temp Hold * 1225 2:00 600 1490
:10 9999 900
** * The initial rate of heat is not a critical factor in successfully striking gold-bearing glasses. Choose an initial rate of heat appropriate to the scale and design of the project that you are firing. ** Remainder of cycle depends on the thickness of the piece. Consult the Bullseye Annealing Chart. For color-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 color results.
Sheet sizes are:
1/2 Sheet - 20" x 17 1/2"
1/4 Sheet - 10" x 17 1/2"
10" x 10"
5" x 10"
5" x 10"s are perfect for testing colors before you commit to buying a larger piece, or if you just need a small piece. **Please note, 5" x 10" pieces may vary in size.**
