Dichroic glass was originally innovated using space technologies. Today, it is used for many other applications including glass art.
Using highly sophisticated and very expensive machines in an extremely controlled environment, layers of metallic particles are methodically deposited onto a plate of borosilicate glass in many different combinations.
The intense and vivid colors you see in dichroic glass are produced by the interaction of reflected and transmitted light bouncing off the crystalline structures coated on the borosilicate.
There are no absorptive qualities in dichroic glass giving light all of its energy to transmit or reflect two extremely vibrant and vivid colors.
