The
“gem” stones in this unique jewelry are composed of many
small pieces of Dichroic and Art or Cathedral glass fused in a furnace
at over 1200 degrees. Most pieces are created individually and are
truly one of a kind.
Dichroic
is a Greek word – “Di” meaning two and “Chroic”
meaning color. This refers to the glass/metal composite's ability
to refract light in different wavelengths (colors) depending on
the angle at which it is viewed. Essentially, a less than micron
thick film of metal bonded to the surface of a glass sheet. This
wondrous material behaves optically much like opal creating a nugget
that throws off a wide range of shifting colors. Depending on the
metal selected and the color of glass, the possible color range
is almost infinite.
The
Dichroic glass material is a spin-off of a very high tech process
perfected in the U. S. space program and utilized to create the
visors on the space helmet protecting our astronauts from solar
radiation. In the case of the visors, they utilize pure gold, coating
a globe of perfect optical glass. The coating process is very complex
in which small sheets of glass are suspended in a vacuum furnace,
the furnace is warmed to about 300 degrees and a crucible of the
selected metal oxide is instantly vaporized by a high intensity
electron beam gun. In the near perfect vacuum, the resulting finely
dispersed fog is evenly distributed throughout the interior of the
furnace, coating all surfaces including the glass with a sub-micron
layer of metal. The resulting coated glass is both reflective and
transparent. This technology is currently used in many fields creating
such diverse products as lighting reflectors, micro circuitry and…mirrored
sunglasses.
