Bullseye Aventurine Bronze (style 001149) is a 90 COE fusible glass sheet, a transparent color for fusing, slumping, and kilnforming.
Working notes This style is categorized as a Transparent glass, though very little light is transmitted through the 3mm sheet. Consistent color. Fusible / Bullseye-compatible. Tiny metallic sparkles, also referred to as spangles, concentrate at the outer surfaces of the sheet glass in the factory-production forming process, including around the rolled edge. The core of the sheet is not metallic.
Reactions This is a reactive glass. It contains Lead (Pb) 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 Double-rolled sheet, 3mm standard thickness, with a rolled edge. 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.
