Many artists have experimented with Dichroic Glass before, but have become disappointed with its characteristics under extreme heating conditions. Some Pyrex workers had actually stopped using Dichroic glass because they claimed it disappeared or became white when hotworked. NOT CBS DICHROIC!! We have supplied several renowned artists with samples of CBS Dichroic Glass and instructed them to “Burn-it-out.” The only damage that was noted to the CBS coating under the most severe conditions was a slight residue formed on the edges. Thus our colors stayed vibrant, our coating remained intact, and the experiment was a true measure of CBS’s solid quality product. We invite all artists to try CBS Dichroic, especially if you have been disappointed in the past with lower quality Dichroic Glass.
