Strawberry - dichroic fused glass cabochonsSold OutSale
This listing is for the cabochons pictured and measurements/ sizing references are in the photos (I use a Canadian quarter and a ruler to give you a visual of the sizes).
I take the first photo from an angled position and the second photo as a top view because dichroic glass colours shift in the light and reflect colour depending on the angle. All photos are taken with natural light to try and grab to most true colours, but I cannot control individual monitor settings.
These pieces are defined as cabochons, meaning the tops are domed (not faceted) and there are no holes or channels in the pieces. They are flat on the back, making them perfect for custom jewelry settings and a wide array of crafting projects.
All my dichroic glass cabochons are made with CBS, Austin Thin Films, and Profusion coatings on system 96 and Wissmach glass (96COE).
What is Dichroic Glass? [dahy-kroh-ik]
When you look at this glass, it appears to have more than one colour at the same time, especially when viewed at different angles. This reflective phenomenon is known as thin-film physics, which is also why you see swirling rainbow patterns in a soap bubble, floating colours from oil on water and the dramatic colours of dragonfly wings.
Multiple ultra-thin layers of different metals (such as gold or silver); oxides of such metals as titanium, chromium, aluminium, zirconium, or magnesium; or silica are vaporized by an electron beam in a vacuum chamber. The vapour then condenses on the surface of the glass in the form of a crystal structure. 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 colours may be obtained.
