Glassblowing is a technique of working with molten glass. The hot glass is gathered from a furnace on a pipe, solid or hollow, and manipulated using a variety of tools at a bench. The glass is only hot enough to be workable for a few seconds at a time and is kept hot by frequent reheating.
Glassblowing is has many similarities with flameworking a key difference being that when working at the furnace all of the glass is hot and has to be kept hot. Furnace glassblowing can be used to make both hollow and solid, functional or sculptural objects.
