||Cascade Glacier |
Item No. 2034
By fusing different metalized dichroics over molten colored frits, we were able to change the character of a dichroic to that of a sparkling glacial stream.
The dichroics pick up the light scattering off the underlying glass creating a blue cascade that sparkles like thousands of individual snowflakes.
Rainbows in nature occur when sunlight refracts while entering and exiting tiny water droplets suspended in the air.
Dichroic glass rainbows are created using multiple micro-layers of rare metal oxides which transmit some wavelengths of light while allowing others to pass through.
This stunning effect produces a transparent array of sparkling colors that change with your viewing angle.
The dichroic glass we use was originally developed for NASA's space program.
But the first dichroic glass actually appeared during the Roman era around 290-325 AD.
The dichroic effect was achieved by adding tiny amounts
of minutely ground gold and silver dust to molten glass.
Ancient dichroic glass is extremely rare and may have been the product of a single studio. It was only around for 100 years then disappeared along with the secret of its manufacture for over a thousand years.
