About
Bullseye Glass has been making tested-compatible 90 COE glass in Portland, Oregon since 1974, and it is the standard for kiln forming. Everything in their line is engineered to fuse together predictably, which is why it dominates fusing studios. It works fine for stained glass too, but never mix 90 COE with 96 COE in a kiln.
