Dichronic Earrings

Invented over 100 years ago and developed in the 1960's as interference filters for use with lasers, Dichronic Earrings glass is a product of the technology called "thin film physics" . Dichronic Earrings glass is used in art glass as well as the laser industry for camera filters, by NASA and various other commercial applications.

Dichronic glass Earrings created at Five Elements Gallery has some of the newest creations. Dichronic Earrings jewelry is made by Alison Thibault in Bucksport Maine. Her designs of Dichronic Earrings including Dichronic Earrings bracelets, earrings and necklaces. So you ask about where some of the fantastic colors which are found only in Dichronic Earring glass art work. There are colors unable to obtain for your glass art work unless you are using the new Dichronic Earrings colors!

The coatings are made with molecular films of metal (primarily silicon and titanium oxides) evenly shuffled into multiple layers. The coating layers of metal oxides make the glass stiffer than other fusible dichronic glass and so requires special handling. The types of metals used and the order in which they are deposited are factors that determine the colors the dichronic glass filters and passes. The dichronic glass must rotate to achieve a uniform coating. This process causes the glass to become a partial mirror by allowing only a select narrow band of light to transmit; other rays are rejected through reflection and absorption. As the light rays transmit through the dichronic glass at a right angle they are less effected by refraction than when passing at an extreme off axis angle where they have to travel a greater distance through the coated material. This greater distance causes a shift of color and when Dichronic Earrings glass is viewed at even slightly different angles, you will see differing colors.

The coatings are produced by depositing thin layers of a variety of dichronic metal oxides such as titanium, magnesium and silicon to the glass in a vacuum. A vacuum chamber is needed in order to produce a pure environment for the vapors to travel. The dichronic materials are vaporized in a crucible by a high voltage electron beam onto the rotating glass above.

When worked in a kiln the dichronic color range shifts on the glass with the heat. By varying the firing temperature different colors can be produced from the same sheet of Dichronic Earrings glass . Each fused Dichronic Earring is truly a unique piece of dichronic art, impossible to duplicate.
