To get this effect, thin layers of metallic oxides, such as titanium, silicon, and magnesium are deposited upon the surface of the glass in a high temperature, vacuum furnace. The glass to be coated is carefully cleaned, and fastened to a planetary arm in the top of the furnace chamber. The oxides are placed in a crucible on the bottom of the chamber. Air inside of the chamber is removed with a high vacuum-producing cyro-pump, and the chamber is heated to 300 °F. The metallic oxides are vaporized by an electron beam, and the rotating glass target is evenly coated with many thin layers. The resulting color is determined by the individual oxide compositions and the coatings sequence, totaling about 700 angstroms thick, (3 to 5 millionths of an inch). All of this is tightly controlled by a computer. Since the total thickness is so minute, the filter has very little mechanical integrity of its own and must be supported on a mechanically stable substrate. Glass is the ideal candidate for this substrate. It is transparent, has adequate rigidity, is stable, withstands relatively high temperatures, and is not affected by moisture, solvents or most acids.

What does Dichroic mean?
if you mean dichroic? it is precious metals ie gold or silver, contained in art glass.
Is The mineral silver used to make glass?
Yes. The iridescent effect that makes glass appear to be different colors from different viewing angles is called dichroic glass. The effect is accomplished by the application of thin layers of silver or gold to the surface of the glass and coating that with another thin glass layer.
What is the Name of a strongly dichroic transparent gem?

What makes glass colored?
It depends on the glass. Some glass is literally stained; that is, painted with a transparent dye. Some glass is colored internally by the presence of small amounts of transition metal compounds. Cobalt, for example, gives a characteristic deep blue; copper can produce a pale blue, and the pale aquamarine of a glass Coke bottle is due to small traces of iron. Finally, some glass is colored by the deposition of an extremely thin film of metal of a very precisely controlled thickness. This is called dichroic glass, and is interesting because the color results from the reflection of certain frequencies rather than absorption. The glass therefore doesn't heat up as much, making this a very popular method of generating color from high-powered theatrical lights (the moving colored lights in rock concerts often use dichroic glass).
Where could one purchase a Dichroic filter?
One can purchase a Dichroic Filter at amazon and way fair. . The price ranges from$33-$76. They come in multiple different colors and sizes. It all just depends on what you are looking for.
What is glass with a 'thin film interference' effect called?
The question isn't quite specific enough to be answered. Glass that has been specially treated to reflect light at particular wavelengths is called a "dichroic filter" (or sometimes a "dielectric mirror", depending on the intent; if you're removing one color to pass the rest, it's a filter, if you're interested in the reflected light, it's a mirror). A more generic term would be "iridescent" glass (or "carnival" glass).
