Bullseye Aventurine Blue (style 001140) is a 90 COE fusible glass sheet, a transparent color for fusing, slumping, and kilnforming.
Cold characteristics Bullseye writes these notes for the standard 3mm sheet of this color; this page is the 2mm thin rolled version of the same glass.
Cold sheet has grainy, sandy surface texture. This style is categorized as a Transparent glass, though little to no light is transmitted through the 3mm sheet.
Working notes Stable, no color shift. Softens more than most glasses at fusing temperature. 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 color is not reactive. It can sit next to any color without forming a reaction line, which makes it a dependable choice for bases and backgrounds. See the Reactive Potential of Bullseye Glass chart to find the colors that do react.
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.
