Kiln Fused / Formed Stained Glass, Bracelet Green/blue color. 1 1/2 inch inch opening. 6 3/4 inches around. 1 inch wide. Strips and or chips of glass are fused together flat in a kiln (1350-1500 degrees), then shaped at 1275-1350 degrees (depends on the type of glass) on a mandrel (wrist-shaped mold) with graphite tongs. Each bracelet is completely unique and each are slightly different in size. They are so much fun to wear and you do not have to take them off in the airport screening process!
