System 96®
Products formulated and "Tested Compatible" especially for fusing, slumping and other hot glass work. This Spectrum line of cathedral sheet glass is complemented by many specialty glass products, including glass frits, noodle, stringer, dichroic glass, and casting billets, made and supplied by System 96 partner companies. All System 96 products are tested against an identical standard to insure compatibility of viscosity and expansion coefficient. Spectrum cathedral colors are transparent letting vision and light travel through which is great for many glass projects.
