Types of Glassblowing
There are two types of common glassblowing.
• Off-hand blowing uses heat and a punty (iron or stainless steel rod) to mold glass. This type requires three different furnaces: a regular furnace to hold the heat, a glory hole to shape and manipulate the glass by heating and reheating, and an annealer to cool the glass to reduce thermal stress.
• The other type of glassblowing is lampworking. A punty and heat are also used in this technique. However, with lampworking an alcohol lamp and bellows are used instead of the furnaces. Lampworking is considered the old-fashioned technique, but is still primarily used for the created of glass beads, glass figurines, glass sculptures, test tubes and miniature glass items.
