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. (co-efficient of
expansion) 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. Though they may look the same as our
stained glass products, Spectrum "Tested Compatible"
glasses are fundamentally different in their basic chemistries,
designed to deliver an excellent working range and superior
stability for glass fusing, slumping and other Hot-Glass pursuits.
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. These items carry the red System 96 logo and have
been "Tested Compatible" to Spectrum Master samples. They
include High-Fire iridescents, special thin glasses, Fractures &
Streamers, a complete selection of Frits, Stringer, Noodles, Casting
Billets and more. A full line of dazzling Dichroic glasses is available
from Coatings By Sandberg (CBS).
 What’s Compatible?
Let the red System 96 logo be your guide to products that have been
"Tested Compatible" within the System 96 program. Most will
carry the manufacturer’s identifying label first, supported by the
secondary System 96 label. We do not recommend mixing products from
outside the program.
Should I Still Test?
We think testing is a good idea, and will continue to recommend it.
Testing is your best teacher. You’ll discover subtle nuances in
different glasses, monitor color shifts, and be better able to predict
various characteristics that may result from the fusing process. Plus,
because our equipment and procedures differ from yours, you just might
uncover a set of circumstances in which our "Tested
Compatible" glasses don’t "work" in your system of
variables. Better to discover that in testing than in a disappointing
project.
