Explore The Elemental Nature Of Dichroic Glass

What is dichroic glass? Dichroic glass is a type of glass that splits and transmits light in two different colors (white and colored). It has been used for decades in many industries, but you're not limited to just clear and colored glasses.

Dichroic Glass Properties

The majority of patterned dichroic glass is made from borosilicate glass. The dichroic properties of this type of glass can be broken down into three main components: a) absorption, b) emission and c) reflection. Each element has its own set of characteristics when it comes to each of these aspects. 

For example, the absorption property or spectrum determines how much light is absorbed by the dichroic glass for each wavelength. If the spectrum is fully absorbed by one element, then that element will only reflect visible light at exactly that wavelength. However, if one element absorbs some wavelengths and reflects others (or vice versa), an overall shift in color can occur.

Why is dichroic glass so popular?

Dichroic glass is one of the most popular types of glass because it has many different uses. It can be used in windows, mirrors, and other objects. Dichroic glass is made of two different colors of glass that are put together to create the desired effect. It is a type of glass that has special properties. This makes it very useful. When dichroic glass is used in windows, it makes the window glow and shine. 

Dichroic light filters can also be used in electronic devices for display such as television screens, computer monitors, and calculators. The display on the device changes depending on the angle of the filter to which it is attached. 

People use dichroic light filters for illumination purposes. They are also used in black lights that change colors when exposed to different types of ultraviolet light. People may use them to decorate their homes or offices by covering windows with different colored dichroic glass panels.


The Making of Dicroic Glass

The most important thing to remember about dichroic glass is that the glass itself is not dichroic. Glass does not produce colors; It is the 'coating' of micro-thin sheets of various oxides and quartz that is applied to the glass surface. This creates an 'interference filter' that acts to reflect or transmit light depending on the oxides used, the thickness of the layers, and other similar factors. Making dichroic glass is a four-step process.

First, the glass is thoroughly cleaned in a spotless environment that, depending on its eventual use, can take up to four cleanings for the glass to meet technical specifications. The slightest dirt, fingerprints, or a water stain can have an unwanted effect on the glass. To buy the best dichroic art glass you may visit

Once the glass is cleaned, the second step is performed: the glass is placed in an oven or a vacuum chamber containing an electron gun and a crucible or container where the metal oxides are stored. Air is pumped, compressing the pressure inside the chamber and, at the right moment, the electron gun is activated, vaporizing the oxides. Vaporized oxides will condense and adhere to any surface within the chamber, especially glass.

Once the desired oxide thickness is reached, the electron gun is turned off and a new oxide is placed for use, if necessary. The process is repeated until the desired thickness of the coating is achieved, or the planned color.

The air is then slowly pumped into the chamber, gradually cooling the molten glass and returning the pressure within the chamber to normal. The vacuum chamber is opened and the glass is removed, inspected, packaged, and shipped.
