How is it done
Glass rods are heated to melting point and wound onto mandrels that have been dipped into bead release. There is also a subcategory of lampworking that is referred to as "off mandrel". Sculptural glass pieces and marbles can be made in this way. Glass is heated using propane and a torch. The most common propane only torch used in lampwork is a Hot Head torch. A dual fuel torch can also be used to melt glass which uses propane and oxygen supplied either from a tank or by an oxycon.
