What is Dichroic Glass…

DichroicDICHROIC is defined as the property of having more than one colour, especially when viewed from different angles. Dichroic glass is a high-tech spin-off of the space industry.
Thin layers of metallic oxides, such as titanium, silicon, and magnesium are deposited upon the surface of the glass in a high temperature vacuum furnace.
Dichroic coatings transmit certain wavelengths of light while reflecting others, thus creating an interference-effect similar to the iridescence observed in Nature’s fire opal or dragonfly wings.
The transmitted colour is different than the reflected colour, and a third colour is produced by viewing the dichroic piece at a 45-degree angle.
The resulting colours are pure, saturated, single wavelengths of light that appear to originate from within the dichroic piece.
