Dichroic glass coatings transmit certain wavelengths of light,
while reflecting others, thus creating an interference-effect
similar to the iridescence observed in nature's fire opal,
dragonfly wings and hummingbird feathers. The transmitted
color is different than the reflected color, and when the
light rays transmit straight through the glass they are less
effected by refraction than when passing at an off axis angle,
which makes the light travel a greater distance through the
glass. It is this distance that causes a color shift. When
dichroic glass is viewed at even slightly different angles,
you will see a variety of different colors as you rotate it.

This dichroic glass piece is 1 1/4" x 3/4". It is sculpted in
14Kt gold filled wire. The completed sculpture is 2 3/8" high,
which includes the bail.
