Bullseye Steel Blue (style 001406) is a 90 COE fusible glass sheet, a transparent color for fusing, slumping, and kilnforming.
Cold characteristics Consistent color.
Working notes Stable. No color shift.
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.
