Bullseye Gold Purple Frit (style 001334) is 90 COE fusible frit, crushed glass in graded grain sizes for casting, layering, shading, and decorative surface work. As a striking color, it may not reach its final shade until it is fired.
Cold characteristics Bullseye writes these notes for the sheet form of this color; the same glass is used to make this product.
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.
Using the frit Bullseye frit is sold in grain sizes from powder to coarse. Powder gives soft, even color and shading, fine and medium build controlled texture and coverage, and coarse gives bold flecks of color and fills for casting and pattern bars. Choose the grain by the effect you want and the fired thickness of your piece.
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.
