Overview
Striker
This style may not reveal (strike to) its target color until fired.
Reactive Potential
Contains: Lead (Pb)
May React With: Selenium (Se) / Sulfur (S)
Forms of Glass
Sheet Glass (-0030, -0050), Frit (-0001, -0002, -0003, -0008) and Billet (-0065)
Detailed Information
About 001831 Sheet Glass
Cold Characteristics
Appears almost clear with blue/purple tint.
Working Notes
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:
This full-fuse schedule effectively strikes these glasses:
| RATE | TEMPERATURE | HOLD TIME |
|---|---|---|
| * | 1225ºF | 2:00 |
| 600ºF | 1490 | 0:10 |
| 9999 | 900 | ** |
**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.
