Dichroic glass is glass that displays multiple colors when viewed in varying light conditions. The changes in color depend on the angle of view. The main use of dichroic glass is for decoration and other forms of art.
Dichroic glass contains several layers of glass fused with fine layers of oxides or metals, such as chromium, gold and titanium. The resulting glass has a crystalline structure that splits the light passing through or reflected by the glass. This causes the glass to display multiple colors when viewed at different angles.
The glass was initially developed as a part of the aerospace technology for use in satellite mirrors. However, the glass is now used in many other fields, such as art and optics.
