Bullseye Gold Purple (style 001334) is a 90 COE fusible glass sheet, a transparent color for fusing, slumping, and kilnforming. As a striking color, Gold Purple may not reach its final shade until it is fired.
Cold characteristics Appears as a dark transparent. May appear to be blue in color.
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.
Reactions This is a reactive glass. It contains Lead (Pb), which is typical for gold struck colors like this one (the gold is the colorant, the base glass carries the lead), and may react where it meets Selenium (Se) / Sulfur (S), forming a visible line or halo at the boundary. Use that on purpose to outline and add depth, or keep reactive colors apart to avoid it.
Format and sizes Thin-rolled sheet, 2mm, with a rolled edge. The thinner sheet is ideal for overlays, fine detail, and controlling stack thickness. Available in the sizes shown above.
Fusing and compatibility Tested compatible with other Bullseye glass. When you combine it with glass from other makers, matching COE alone does not guarantee compatibility, so fire a small test tile first.
