COE: 96 This glass can be mixed and fused with any glass that is the same COE. COE measures how quickly a glass expands and contracts during the fusing processes. All glass that is "melted" or fused into a single piece must be compatible.
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. Though they may look the same as their stained glass products, Spectrum "Tested Compatible" glasses are fundamentally different in their basic chemistry, designed to deliver an excellent working range and superior stability for glass fusing, slumping and other Hot-Glass pursuits.
