Double Helix Arke Rods
Arke can develop exterior metallic finishes of silver, gold, green, red and blue.
Variations
in flame chemistry, exposure time and temperature alter which metals are
deposited on the surface of the glass. The green metallic finish in the
stock 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 repeated reduction. Contrast between these metallic finishes
can be highlighted 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, building metallic layers of alternating composition.
