Jewellery Guides - Dichroic Glass

Dichroic glass is a highly skilled process involving a vacuum deposition method. The appearance of dichroic glass is quite distinctive, being two or three tone, depending on the angle of the glass or the shift of light reflecting on the surface. One colour is transmitted through the glass when viewed straight on and another colour may be reflected off the glass when placed against a dark background. Angling the glass will display shades that vary between the transmitted and reflected colours.

This rainbow effect is a product of the process known as 'thin film physics', a technology also responsible for the rainbow colours reflected by oil slicks in puddles and the iridescence of soapy bubbles. Dichroic glass is created in a vacuum chamber, where micro-layers of metallic oxides of selenium, zirconium, titanium, chromium and manganese are vapourised using a high-voltage electron beam and then coated to molten glass.

The literal meaning of dichroic is 'two-coloured' and is derived from the Greek words 'di' meaning two and 'chroma' meaning colour. It is pronounced dye-croy-ik and is commonly misspelled as dycroic, dychroic, dicroic... Sometimes dichroic glass is confused with fused glass. Although fused glass has some overlap with dichroic glass and sometimes incorporates dichroic glass elements, this is not essential.
