Exclusive daylight iridescent "glowing" Laser Optic coatings create dichroic glass - they actually appear to glow in ordinary room light. These produce beautiful blues and green hues.
From the 'Inner Glow' Collections these crystal sea shells contain 45% leaded crystal for unique optical properties, fine detailing as opposed to 38% in Austrian crystal.
These Dichroic Crystal Glass Sea Shells are individually hand-cast (adapted from a casting method originally developed by the ancient Egyptians to make gold jewelry) and molded from actual sea shell specimens - shell collectors LOVE these!

"Dichroic" is defined as the property of having more than one color, especially when viewed from different angles. Thin layers of metallic oxides in precise thicknesses, such as titanium, silicon, and magnesium are deposited upon the surface of the glass in a crefully controlled vacuum in a high temperature 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 cyropump, and the chamber is heated to 300 degrees Fahrenheit. 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.
