Bullseye Midnight Blue Stringers (style 001118) are 90 COE fusible stringers, thin rods of glass for drawing fine lines, outlines, and linear detail on fused work.
Cold characteristics Bullseye writes these notes for the sheet form of this color; the same glass is used to make this product.
Uniform 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, so it works well as a dependable base or background. See the Reactive Potential of Bullseye Glass chart to find the colors that do react.
Using the stringers Stringers are thin, uniform rods you lay on the surface to draw lines, borders, lettering, and fine detail. They fuse flat into the glass and can be snipped, bent with a little heat, or arranged into patterns before firing.
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.
