Bullseye Teal Green (style 000144) is a 90 COE fusible glass sheet, an opalescent color for fusing, slumping, and kilnforming.
Cold characteristics Some light/dark variations common on surface.
Working notes Light/dark variations generally disappear on firing. Dark interface reaction likely with sulfur glasses (001137, 001437, 000137). Read “Reactive Potential of Bullseye Glasses” to learn more.
Reactions This is a reactive glass. It contains Copper (Cu) and may react where it meets Selenium (Se) / Sulfur (S), Reactive styles (000009, 001009, 001019), 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 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.
