Bullseye tints are great for casting and on edge work. They provide subtle color to the finished piece.
Keep in mind that striking glass matures to a much different color when fired. The final color will vary depending on temperature, atmosphere, and heat history. This allows a broad range of color to be obtained from a single sheet of glass.
Striker. Contains Lead, May React With Selenium, Sulfur.
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 1225F 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.
