This beautiful piece of glass which looks like vibrant peacock feathers was made using a technique called Combing.  Individual pieces of glass are cut 3/8 inches wide and 8 inches long, then laid cut end up in the desired pattern.  The piece is supported by dams to keep the glass from flowing while in the kiln.  Once the kiln is approximately 1700 degrees it is carefully opened and a stainless steel hook is dragged through the molten glass.  Each drag of the hook requires the kiln to return to 1700 degrees.  Although this piece has straight lines pulled through it, it is also possible to pull wavy lines in the molten glass creating really interesting patterns.  This is a really fun technique but definitely not for the faint of heart… the kiln is very hot when opened at 1700 degrees !
