Arke is described as having exterior metallic finishes of silver, gold , green , red and blue.
The green metallic finish in the photo was achieved using a "hot" reduction flame. The silver tone resulted from brief exposure to a "cool" reduction flame, while the red tones were developed by using a small oxidizing flame to remove the metallic luster from selected portions of the bead, then re-exposing the bead to a reduction flame.
