Dichroic glass is a clever discovery brought to us by those boffins at NASA. It's a metal oxide coating on glass that has unique properties. It can allow through it one way but can block it coming through on the reverse side. That all sounds very dull but basically it makes things shimmer. The metal oxide coatings come in a wide range of stunning colours and with this unique play with light, they look simply stunning as items of jewellery.

There are a few ways to spot genuine dichroic glass. Because the light acts so remarkably on the surface it can appear to change colour when you view the piece from an angle. Exposed dichroic glass, that is, dichroic without a clear top layer will appear to be metallic even though it is glass.

Dichroic Jewellery like all types of fused glass is produced in a kiln. Glass fusers use specifically designed kilns that are thinner than the types used by ceramic artists generally because the items produced by glass fusers are thinner and the firing cycle means it is more economical to do so.
