Bullseye Light Cyan Stringers (style 000216) 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.
Very slight orange-peel mottling.
Working notes At full fuse, capped or uncapped, the mottling disappears and the color is consistent, even and pure. At slumping temperatures and low-tack fusing temperatures (1150-1325°F/621-718°C), gray clouding may occur, similar to Steel Blue Opalescent (000146), especially where contamination from oils and/or cleaner is left behind during the cleaning process. Solution: cap this color with clear or test for each specific application. The clouding can be erased from an uncapped piece by capping with clear glass and firing to a full fuse.
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.
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.
