Dichroic Glass
Dichroic (meaning 2 colours) glass was originally developed as a way to put a metallic coating on glass for the US space industry. It has the unique property of reflecting one colour while transmitting another colour. By shifting the glass at different angles, you will see two different colours. It's produced by spraying thin layers of metallic oxides (such as titanium & magnesium) onto the glass surface at very high temperatures in a vacuum furnace. Dichroic glass is one of the most expensive types of glass available. Although expensive to make, the beauty of dichroic glass has made it popular for jewelry and for decorative additions to kilnformed glass. |
