Frequently Asked Questions

What does “dichroic” mean?

Dichroic (pronounced "dye-crow-ick") glass, commonly called dichro for short, literally means "two colored." It is derived from the Greek words "di" for two, and "chroma" for color. It was thus named because of its fantastic multicolored and reflective properties.

When you look at this glass, it appears to have more than one color at the same time, especially when viewed with different lighting.

This reflective phenomenon is known as thin-film physics, which is also why you see swirling rainbow patterns in a soap bubble, floating colors from oil on water and the dramatic colors of dragonfly wings.
