NASA developed dichroic glass for use in satellite mirrors. Dichroic glass is a multilayer coating that is placed on black or clear glass using a highly technical vacuum deposition process.
Some colors have multiple of these layers, however, the depth of the entire layer is approximately 35 millionths of an inch.
Dichroic coatings transmit specific wavelengths of light, while reflecting others, thus developing a similar effect, such as the iridescence found in the fire pit, dragonfly wings, and hummingbird feathers.
CBS dichroic glass has 2 main colors and several other secondary colors. The transmitted tone is noticeable if the glass is held up to the light and the reflected color is noticeable while the glass is placed against a dark background. Since the glass is transferred, several different colors will be seen.
Portable glass art became one of the most popular fashion accessories today, among people who are on the Internet or looking at the display in galleries, shopping malls, and the like.
'Wearable' glass is fused glass, technically known as CBS dichroic patterned glass, which is glass in which various oxides or quartz combine on the surface in different layers or thicknesses to produce a multi-colored effect.
Dichroic glass is a NASA innovation, initially made for use in spacesuits and later used by different companies such as optical companies (different video cameras have used video-based lenses), technological measurement tools (particularly those that use lasers for sizing), and many others.
