Here is the most sophisticated glassblowing process used to make the simplest of all forms: a cylindrical tumbler. The second most important tool after the invention of the blowpipe, the soffietta is used to make the work easier with better results.
(Italian) A tool used as a puffer to further inflate a vessel after it has been removed from the blowpipe and is attached to the pontil. It consists of a curved metal tube attached to a conical nozzle. The glassblower reheats the vessel, inserts the nozzle into its mouth so that the aperture is blocked, and then inflates the vessel by blowing through the tube.
An iron or steel tube, usually four to five feet long, for blowing glass. Blowpipes have a mouthpiece at one end and are usually fitted at the other end with a metal ring that helps to retain the gather.
Any instrument used by glassworkers to develop and shape an object. Glassworkers’ tools include the blowpipe, pontil, gathering iron, jacks, shears, clapper, pallet, block, pincers, battledore, lipper, and crimper.
