Topics: Dichroic Glass

Q.
What is dichroic glass, and how is it pronounced?
- Taylor
A.
Pronounced /dí-kró-ic/, dichroic glass was developed by NASA and the Department of Defense and their contractors to help protect sensitive spacecraft instruments from cosmic radiation. It is a glasswork technique, either with blown glass, fused glass or glass beads, which are vacuum coated with many layers of metal oxides which give the glass its luminous multi-color and 3-dimentional look. The word comes from the Greek "Di" for two and "Chroma" for color, as often the dichroic technique is viewed at different angles which gives the appearance of two or more colors.
