Spectrum offers a broad line of specially formulated "Tested Compatible" glass for the Hot-Glass arts. These products have been Expansion-Matched to a nominal C.O.E. of 96, then factory-tested for fusing compatibility. Each glass has been carefully formulated for Multi-Fire devit resistance, and every sheet is clearly marked with a Spectrum "Tested Compatible" label.

System 96
In partnership with other suppliers, Spectrum "Tested Compatible" products serve as the core of a complete Hot-Glass program called System 96®. Our friends at Uroboros Glass Studios have produced specialty glasses designed to work harmoniously with the Spectrum products.

Note: NOT compatible with Bullseye products!
