Gold Purple Opal (334) 3mm
Gold Purple is a striking glass. Matures to a consistent gold/purple. Contains lead and may react to sulfur 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”
Sample: 2 1/2” x 3”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.**
Our Samples are larger than Bullseye’s in order to give you a better sense of the color. Keep several on hand to create color palettes and test transparent layers. Strikers will come pre-fired so you can see the fully developed color. Samples available in 3mm Opals, Collage, or 3mm and 2mm Transparents.
