Dichroic glass is glass containing multiple micro-layers of metal oxides which give the glass dichroic optical properties. The invention of dichroic glass is often erroneously attributed to NASA and its contractors, who developed it for use in dichroic filters. Dichroic glass dates back to at least the 4th century AD as seen in the Lycurgus cup.
Multiple ultra-thin layers of different metals (gold, silver), metal oxides (titanium, chromium, aluminum, zirconium, magnesium) and silica are vaporized by an electron beam in a vacuum chamber. The vapor then condenses on the surface of the glass in the form of a crystal structure. This is sometimes followed by a protective layer of quartz crystal. The finished glass can have as many as 30 to 50 layers of these materials yet the thickness of the total coating is approximately 30 to 35 millionths of an inch (about 760 to 890 nm). The coating that is created is very similar to a gemstone and, by careful control of thickness, different colors are obtained.I love working with dichroic glass, just not really good at making any beads or pendants; however I’m in luck! A very good friend and fellow artisan Anna is a premier glass designer here in San Antonio, Texas. She makes some of the most incredible, gorgeous dichroic one-of-kind pieces (I know, I personally have quite a few of her pendant sets!). I buy her pendants and incorporate them into my own creative designs; accenting with wire, metals, crystals, or natural stones; drawing on the colors of the pendant to develop the jewelry.
These two designs are using Anna’s pendants as a focal and then using the different wire and charm techniques to showcase the beauty found within each individual pendant.
In the first design, I use a free form shaped pendant that is hung below the crystals from non-tarnish brass wire as a bail. I’ve then accented with individual hand-charmed pieces in black agate, beige freshwater cultured pearl nuggets, creamy white glass pearls, and faceted swarovski crystals in erinite and indicolite. The creation hangs from an eggshell colored silk cord in a stationary position. There are little hints of wire in hanging swirls also handcrafted in non-tarnish brass wire.
The second piece I chose a nice almost arrowhead shaped pendant with accenting designs in gold, green and hint of blue against a black background. Surrounding it again are hand-charmed pieces in faceted swarvoski crystals indicolite, cosmo black, gold/black Diablo, gold, citrine, ab smoky topaz, and metallic green-blue. The all are braided on a 6 strand ribbon cord necklace; I left them a little lose as this fit better to this type of a design, you can twist the crystals around to change the colors slightly. Hidden among the crystals are a few handmade wire spirals in non-tarnish brass wire.Find these and many other uniquely artisan crafted designs at our online shop!
