What Are Fused Dichroic Pendants?

You may have seen beautiful jewelry described as "bi-colored" and wondered what exactly that means? Dichroism comes from the Greek meaning two colors. The glass appears in different colors when viewed from different angles or with varying degrees of light. Basically, it means that dichroic glass reflects one color when light is reflected from the surface and transmits a second color when light passes through it.

Dichroic glass today is an offshoot of the space program as it has been used in face panels to filter out unwanted spectra of light. Dichroic glass today has many different applications from fine jewelry used by artists to the optical and security industries. You can find the etched dichroic glass from Art Glass Supplies.

The process used to make dichroic glass is very technical and is called "thin-film physics". It is an expensive process in which glass is first cleaned to the molecular level and then coated with thin films of elements such as titanium, magnesium, zirconium, and others. Elements are deposited by vacuum on glass. Up to thirty layers can be applied and the elements used to give the glass the different colors available. The time required in the vacuum vessel can take from two and a half to four hours, hence the reason for the high cost of this unique glass.

Artist's glass is sold as small sheets that are hand-cut to fit the artists' design and baked in an oven for eight hours or more at temperatures that can reach 1,490°C. Dichroic glass is also available in lamp artist glass rods to produce beautiful beads. Lamp artists use a torch and rods of glass to produce the beads on a mandrel that is also placed in an oven for about an hour to solidify.

Choosing Glass For Your Stained Glass Artwork

Options range from the cathedral to ancient times. Cathedral stained glass windows are more commonly used than old ones, which can be difficult to find and expensive.

There is a wide variety of different types available. It also comes in a large selection of colors, transparencies, and textures. Other determining factors when choosing are coatings and ease of cut.


Some of the common manufacturers include Spectrum, Wissmach, Bullseye, Kokomo, Youghiogheny, Uroboros, and Van Gogh. Your project can be made from one manufacturer or a combination of different manufacturers. Spectrum tends to be the easiest to cut. Using a combination of different manufacturers on one piece tends to enhance your artwork. For more information about iridescent glass visit


Although most glass is smooth, you can also choose to use textured glass. Textures range from subtle to dramatic. The more textured, the more care is needed when cutting. Textured, one side is usually more textured than the other. You should cut on the softer side. Some of the common textures include rough laminate, hammered, granite cracked, and water glass (trademark of Spectrum). Using a variety of textures adds movement and dimension to your artwork.

Glass coatings

Glass liners add design elements. The types of coating used can include; iridescent, mirrored, matte, sandblasted, engraved, and metallic. The iridescent coating has a metallic sheen and creates a rainbow effect. The darker the sheet, the more distinctive the rainbow effect will be. Adding coatings to your artwork will change the feel of the piece. It is amazing how a covering accent can enhance the artwork.
