Bullseye Burnt Scarlet Tint (style 001823) is a 90 COE fusible glass sheet, a transparent color for fusing, slumping, and kilnforming. As a striking color, Burnt Scarlet Tint may not reach its final shade until it is fired.
Cold characteristics
Appears almost clear with blue/green tints.
Working notes
Color usually deepens on firing. Possible dark interface reaction with selenium and/or sulfur glasses (000137, 001122, 001125, 000124, 000125, 001137, 001437). Less viscous (softer) than most other glasses. Some striking glasses that use gold as their coloring agent, like this one, must be fired with a 2 hour hold in the range of 1200-1225°F during the initial stages of the firing cycle in its first firing to properly develop their color. If fired without this hold, or in a kiln that runs hotter than average, they may not strike at all, or they may strike but appear spotty and have a blue-brown cast, as opposed to their intended color. We have found that holding at 1200°F for 2:00 offers consistent color development with this style across a range of kilns and production dates, and functions as an adequate bubble squeeze for most projects. If your work depends on a bubble squeeze at 1225°F we recommend doing a small test on this style and other striking transparent pink glasses before beginning a project as they require precise heating to strike properly. For full information and testing strategies see the article Properly Pink, Purple and More.
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.
