Lampwork beads are made by winding molten glass around a steel mandrel. The reason it is called "Lampwork" is because early glass beadmakers in Venice used oil lamps as their heat source to melt their glass. Today a torch is used. Each bead starts as a rod of glass that is melted at about 2000 degrees and wound onto a steel rod. Designs are then applied using more molten glass in various colours creating unique one-of-a-kind treasures.
