3/4 x 4 inch strip of candy magenta/green dichroic on 1/8″ thick clear boro. The photo shows dichroic fired over black, white and clear rods. When working dichroic, keep the coated side of the glass away from the flame to keep the dichroic surface most vibrant.
Dichroic Glass made by Coatings by Sandberg is a multi layer coating placed on glass by using a highly technical vacuum deposition process. Quartz Crystal and Metal Oxides are Vaporized with an electron beam gun in an airless vacuum chamber and the vapor then floats upward and attaches then condenses on the surface of the glass in the form of a crystal structure. Our colors have as many as 30 layers of these materials yet the thickness of the total coating is approximately 35 millionths of an inch. The coating that is created is very similar to a gemstone and by careful control in thickness, different colors are obtained. Thus, all our coatings are created using the same exact materials. Originally created for the Aerospace industry, Dichroic Glass is now made available to the artist community through Coatings By Sandberg, Inc. CBS Dichroic Glass is specifically designed to be hotworked in any way but can also be used in its raw form. The main characteristic of Dichroic Glass is that it has a transmitted color and a completely different reflective color. Furthermore, these two colors shift depending on angle of view. With the play of light together with its vibrant color, Dichroic Glass is a prime tool used to add interest to any piece of work or project.
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.
Our dichroic glass does not burn out!
