Spectrum creates the popular coefficient fusible glass in COE 96. This glass is the ideal kiln-forming product, because it resists common divitrification issues, and does not "strike" colors- meaning, in most cases, the color you see before firing is the same color you see after firing. These colors are compatible for fusing with any other COE 96 manufacturer, including Uroboros, Wissmach, and Youghiogheny 96 product lines. Come in for the full selection in store.
