Fused and Slumped Glass ToBs: the process

Fusing and slumping is a two stage process. First, on a flat kiln shelf, a design is assembled from coloured (or stained glass).  The shelf is placed in a kiln and heated until the glass melts, or fuses (around 1500F), into one single piece of flat glass.  Second, after the kiln cools, the fused piece is removed and sometimes ground or sandblasted, then placed onto a mold.  Mold and glass are then returned to the kiln and fired until the glass bends or slumps to the desired shape.
