Dichroic is defined as the property of having more than one color especially when viewed from different angles or when transmitted to reflect light. Dichroic coated glass is produced by a process called "thin film physics" and is generally referred to as a color separator. It"s normally used as an interference filter in scientific measuring or correcting applications. 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. They are then fired up to 1500* after being set between a solid bottom piece of glass and a clear piece fired over a dichroic piece or a grouping of many pieces either flat or layered together. Overnight they cool to properly anneal to gain their strength. The beauty of the finished product can then be transformed into a beautiful piece of wearable art.
