Dichroic Glass Pendants

 Dichroic glass is a type of glass that exhibits various colors based on lighting conditions. It is a product of materials research by NASA and its contractors, originally developed for dichroic filters. The glass is created by vaporizing multiple ultra-thin layers of transparent oxides (such as titanium, chromium, aluminum, zirconium, or magnesium) or silica using an electron beam in a vacuum chamber. The resulting crystal structures are hand-cut, layered, and fired in a kiln at temperatures exceeding 1400 degrees to produce the final visually striking product.
