Q: what is genuine dichroic glass (this does not include glass from china or asia as most of the glass from there is not actually dichroic but just foil and nothing to do with dichroic glass at all they just call it dichroic to mislead people, so if it doesnt say its "GENUINE" DICHROIC GLASS then it probably isnt, and should be avoided)
A: Genuine Dichroic Glass is an expensive multi-layer coating placed on glass by using a highly technical vacuum deposition process. Quartz Crystal and Metal Oxides are vaporised onto the surface of the glass in the form of a crystal structure. Dichroic Colours 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 colours are obtained. Thus, all dichroic coatings are created using the same exact materials. Originally created for the Aerospace industry, Dichroic Glass is now made available to the artist community from Coatings by Sandberg (CBS).
The main characteristic of Dichroic Glass is that it has a transmitted colour (where light passes through the glass) and a completely different reflective colour (where light reflects off the glass). Furthermore, these two colours shift 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. Uk artists have unlimited freedom of expression with this sparkling medium. dichroic glass is a fabulous addition to anyones jewellery box.
