lampwork

Lampworking is a glassworking technique in which glass is melted and shaped with a flame from a handheld torch. Artists typically work with glass rods or tubes, heating the material until it is malleable and then forming it by twisting, winding, and blowing with tools, gravity, and mandrels. The process is commonly used to create small objects such as beads, components for jewelry, sculptures, and decorative pieces. Lamps and furnaces are used in historical contexts, but modern lampworking relies on gas-fueled torches and careful control of heat.

Historically, lampworking dates to ancient civilizations that used oil or gas flames to manipulate glass. The craft evolved in Europe and the United States, with significant development in beadmaking and glass sculpture in the 19th and 20th centuries. Contemporary lampworking is practiced by studio artists and hobbyists worldwide, often focusing on color work, detailed glass canes, and complex patterns.

Techniques include shaping with steel or graphite tools, using mandrels to form hollow beads, encasing different colors, and employing frit, canes, and murrine to create patterns. Glass types commonly used are soft glass (soda-lime) and borosilicate glass; borosilicate requires higher temperatures and different equipment. The artist typically mounts the work on a mandrel during shaping and anneals finished pieces in a kiln to relieve stress, then may cool gradually.

Equipment includes a blowtorch or micro-torch, a workbench, shaping tools, glass rods, mandrels, and a kiln or annealing oven. Adequate ventilation, heat protection, and eye safety are essential due to high temperatures and fumes. Beginners are advised to learn under experienced supervision and follow safety guidelines.

Lampworking supports a range of styles from beads and jewelry components to sculptural objects, and remains a popular form of studio glass art.
