Dichroic Glass

A very special type of glass, known as dichroic, which changes colour when held up to the light.

Dichroic Glass 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.

A sheet of Dichro Glass many have as many as 40 layers applied yet the thickness of the total coating is approximately 35 millionths of an inch.

Originally created for the Aerospace industry NASA

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 giving it its mesmerizing and attractive quality

Most large sheets of dichroic glass are round due to the manufacturing process. The large sheets must rotate during the coating process to achieve a constant uniform color across the surface of the sheet. They are then cut down and sold in smaller squares.

We have a large range of dichroic glass on sale and have produced a series of glass fusing video tutorials in which we use dichroic glass to create wonderful pieces of jewellery in a microwave oven using a microwave kiln, ideal for jewellery making at home.
