~~Lampworking is a type of glasswork where a torch is used to heat rods of glass until molten, then the glass is wound around a coated steel mandrel to form a base bead. The bead is then embellished using a variety of techniques and materials. When finished, the bead must be “annealed” [slowly cooled in a kiln] to prevent cracking or shattering. Early lampworking was done in the flame of an oil lamp, with the artist blowing air into the flame through a pipe. Artists today use torches that burn propane or natural gas.
