KincaiDesigns defines dichroic glass as a glass that contains ultra thin layers of aluminum, chromium, silcon, zirconium, or the metal alloy titanium. The colors are almost holographic in appearance. Metallic oxides are bonded to the glass using an electron bombarder inside a vacuum chamber under strict laboratory conditions. Once the coating has adhered to the glass it is fired in a kiln to make the coating permanent. The angle of the glass in the chamber determines the color. In actuality there is no color produced! What you are seeing is pure light manipulation. The appearance will be different depending on whether the light is reflected or transmitted.
This very technical definition doesn’t do justice to the beauty of dichroic glass. Artists and craftsmen then take this amazing glass and create awesome works of creativity.
