This is glass which has been coated on one side with metal oxide layers. These oxides are vaporized and deposited on the glass surface in a vacuum chamber, by heating the metal oxides between 1,000 & 2,500 degrees Celsius. The thickness of each layer is precisely calculated within five millionths of an inch. By building up multiple layers of different oxides, a wide range of reflected and transmitted colors are produced. Dichroic means two color, and each piece of this glass will reflect two different colors, depending on the angle light strikes it. Because of the specialized manufacturing, this glass can cost ten times more than plain glass.
Specially coated glass used as decorative additions in art glass. After extensive cleaning, glass is placed in a heated vacuum chamber. In the chamber the surface of the glass is blasted with an electron beam gun, which coats the glass with different metallic oxides and rare metals to create different patterns and color effects. Two different types of base glass are used in the process. When used in the first or transparent state, both reflected and transmitted light frequencies are emitted. In the second phase a dichroic coating on a black background makes the surface color reflect. Unique colors are reflected and transmitted like teal or champagne, and the thin coatings of metals simulate precious metal qualities like those of copper, gold, platinum or silver on the dichroic surface.
A type of glass that reflects and transmits different wavelengths of light, thus visually appearing as different colors in reflected and transmitted light. The dichroic effect is achieved by coating thin layers of various chemicals or metals on the surface of clear glass.
This is an enchantingly beautiful glass. Under laboratory conditions of high heat and vacuum, various metallic oxides layered over the glass creating fascinating effects. The reflected light appears as a shiny opaque color; and when light passes through it, the color changes and becomes transparent! This glass is expensive, but well worth the price. It also requires a special technique of heat application or it will burn to an ugly ash.
Glass that is one color when seen by reflected light and another color when light shines through it. This is sometimes due to the presence of minute quantities of colloidal gold.
Dichroic means two colors, and this glass appears to be different colors when viewed from different angles or in varying degrees of illumination. Dichroic glass is created by adding a thin layer of metallic oxides which transmit certain light wavelengths while reflecting others, causing an iridescent effect.
Glass that appears different colors when light is reflected or transmitted.
This great material is often used in the making of cabochons. It is very attractive and amazing when viewed in the light. Pieces of glass are carefully arranged and layered, then placed in a kiln and heated.
A thin metallic coating on any type of glass; the coating is applied at a high temperature in a vacuum chamber.
The brilliant dichroic optical properties of dichroic glass are the result of multiple micro-layers of metal oxides. These thin layers of oxides have a total thickness of three to five millionths of an inch.
