Cold characteristics Bullseye writes these notes for the sheet form of this color; the same glass is used to make this product.
Varies slightly from lighter to darker.
Working notes A sulfur glass. May have dark interface reaction with copper-bearing (001116, 001408, 001417, 000116, 000144, 000145) and lead-bearing (001311, 001215, 000301, 000305) glasses. Learn more about possible reactions by reading our Reactive Potential of Bullseye Glass chart.
Reactions This is a reactive glass. It contains Sulfur (S) / Selenium (Se) and may react where it meets Copper (Cu), Lead (Pb), and Silver (Ag), 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.
