Dichroic glass is a high-tech spin-off of the space industry. "Dichroic" is defined as the property of having more than one color, especially when viewed from different angles or from transmitted to reflected light. Dichroic coated glass is produced by a process called "thin film physics" and is generally referred to as a color separator. To get the effects, thin layers of metallic oxides, such as titanium, silicon and magnesium are deposited on the surface of the glass in a high temperature vacuum furnace.
The piece you see here is formed from three layers of glass, one base, the middle dichroic and a clear topper and then is fused, shaped and finished.
