Bullseye Dense White Stringers (style 000313) 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 This glass can be unstable when subjected to extended heatwork (pattern bars, pot melts, boiled effect, kilncasting, etc.). Firing above 1500°F (815°C) for more than 15 minutes or firing slowly between 1250°F (677°C) and 1500°F (815°C) may result in an unstable glass. More susceptible to contaminants that seed devitrification than other glasses in the Bullseye line. Cap with clear or plan to treat the surface (sandblast, coldwork, or apply clear powder and refire) after firing. No color shift upon firing. A dark interface reaction is possible with sulfur/selenium-bearing glasses, notably French Vanilla (000137). Dense White does not react broadly across the sulfur/selenium palette. Dense White Powder (000313-0008F) is recommended for surface use only. It may crackle when used between sheet glass layers.
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.
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.
