WHAT IS DICHROIC GLASS ?                 RETURN TO SYSTEM 96 MENU PAGE
Dichroic Glass is a multi layer coating placed onto a glass surface by using a highly technical vacuum deposition process. Quartz crystal and metal oxides are vapourised with an electron beam gun in an airless vacuum chamber. Tthe vapour then floats upward, attaches, then condenses on the surface of the glass in the form of a crystalline structure. CBS colours have as many as 30 layers of these vapourised materials yet the thickness of the total coating is approximately 14 millionths of a millimetre. The coating that is created is very similar to a gemstone and by careful control in thickness, different colours are obtained. All coatings are created using the same exact materials. Originally created for the Aerospace industry, Dichroic Glass is now made available to the artistic community. 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 colour and a completely different reflective colour. A two colour shift is noticed depending on angle of view. With the play of light together with its vibrant colour, Dichroic Glass is a prime tool used to add interest to any piece of work or project. Over 45 colours of Dichroic Coatings are available to be placed on “any” substrate (ie glass), giving artists unlimited freedom of expression.

PUT CBS DICHROIC GLASS IN THE FIRE
CBS Dichroic Coatings are specifically designed to be hot worked. CBS coat their glass for use in Glass Blowing, Flameworking, Fusing, Slumping, Beadmaking and any other technique that involves the manipulation of glass with extreme heat.

CUTTING DICHROIC GLASS
The Dichroic Coating does not affect the integrity of the glass in any way. We recommend that you cut / score the glass on the "UNCOATED" side of the glass substrate. This will produce a much smoother and cleaner break.

SCRATCHING DICHROIC GLASS
The quality Dichroic surface is stronger than the glass surface that it has been coated onto. The final layer that CBS adhere to the glass is Quartz Crystal (This material is almost as strong as an actual diamond. However as it is extremely thin, the glass and the coating can be scratched if care in handling is not taken. CBS do not recommend using abrasives such as steel wool etc. When grinding the edge of the glass, the coating will be removed along with the glass that is also being chipped off. CBS recommend using a fine grit grinding wheel to try to keep chipping to a minimum.

ARCHITECTURAL APPLICATIONS
There is an ever growing demand for the use of Dichroic Glass in architecture. Its resilience to weather and never-fading colours are prime material to enhance office buildings, decor in homes, walkways, fountains, skylights, walls, lighting fixtures and more.

TRANSMISSION VERSUS REFLECTION
The "Transmitted Colour" is the colour you see through the glass. The "Reflected Colour" is the colour you see in a clear or opaque piece of glass when the light bounces or reflects from the surface of the glass. Most of CBS colours are listed with the Transmission Colours then the Reflected Colour. For example "Blue / Gold" will be Blue in transmission and Gold in reflection. With a CBS coated black / opaque sheeted with Blue / Gold dichroic, you would only see its reflection of Gold (Yet, it is still called Blue / Gold).
