Dichroic (die-crow-ik) glass is a speciality glass developed in the 1950s by the aerospace industry. Dichroic refers to the property of having more than one colour when viewed from different angles. In a lengthy and costly procedure, thin layers of metallic oxides are deposited on the surface of the glass giving an extraordinary selection of vivid colours. Glass artists have only recently begun to exploit these amazing properties. The glass used in the jewellery is cut, layered, then kiln fired repeatedly in extreme heat to produce the desired stunning textures, colours and shapes.
