About Dichroic Glass

"I have been specializing in dichroic glass for many years being unlimitedly fascinated by its elusive properties of multidimensional iridescence and opaline depth. I am enjoying trying to break boundaries and use dichroic glass in different manifestations. Piecing intricate designs together further the already multidimensional dichroic properties. I have a lot of pleasure incorporating the 22 K gold decals over many of my designs to form my themes and various familiar iconic scenes."

"I am hoping my customers share in the strong meaning and find personal identification with my jewelry pieces. Please enjoy browsing through my site and thank you for visiting."

What is DICHROIC GLASS?

The technical definition of dichroism is an optical effect observed in certain crystalline materials, in which two different colors are seen when the crystals are viewed in different directions. Dichroism is observed only in colored materials, -- more so in deeply colored than in pale substances. The base, or preliminary color of dichroic glass is identified by viewing the glass straight on in transmitted light. When the glass is turned about 45 degrees, the glass shifts to its secondary color. When there is no transmitted light, the coating becomes a third color in reflection. This is the main reason it is difficult to explain or photograph the mysterious beauty of the alternating colors. When dealing with dichroics, we refer to either Additive (red, green & blue) or Subtractive (yellow, magenta & cyan) colors. To obtain a green transmission of light, both red & blue rays need to be reflected. The right combination of red & blue can appear pink. When the conditions of light are such that you can see through the glass, and the color is green, the same piece will appear pink when looking at the reflection.

MANUFACTURING DICHROIC GLASS:

The base glass is polished with rouge, then cleaned to the molecular level with several types of solvents. The glass is then coated with extremely thin films of elements, such as titanium, magnesium, zirconium, etc. The elements are evaporated and vacuum deposited onto the glass to such a fine degree of thickness that certain wavelengths of light will pass through and others will be reflected. The light rays which do get through the coated glass appear to take on the color characteristics of the coating. Up to twenty layers of materials such as Beryllium, Chromium, Selenium, Yttrium and Tin are used. The Laws of Refraction as well as the differences in Refractive Indexes between air, glass, and the coating layers dictate how and why the glass changes color when viewed from different angles.

DICHROIC GLASS COLOR RELATIONSHIPS:

Transmitted color is the color you see when looking through the glass, if it is on black glass the transmitted color is completely absorbed and only the reflected color is viewed.
The reflected color is the color reflected back or not absorbed by the glass.
Shift color is the change in the reflection color of the glass after it has been heated; dichroic glass shifts towards the next lighter color traveling towards the purple end of the spectrum. The shift depends on the highest temperature the glass is exposed to, how long the exposure is, the particular coating used and how many times the glass has been fired. Viewing the raw glass at a 45 degree angle gives a representation of the color achieved after firing.

[1] Transmitted Color / [2] Shift Color / [3] Reflected Color

Magenta - shifts to Yellow - reflects Teal Green
Blue - shifts to Magenta - reflects Gold
Cyan - shifts to Turquoise - reflects Red Orange
Yellow -shifts to Clear - reflects Blue Purple
Red - shifts to Orange - reflects Silver Blue
Orange - shifts to Yellow orange - reflects Blue
Green - shifts to Blue - reflects Hot Pink
Yellow/Green - shifts to Turquoise - reflects Violet
