A stage in the manufacture of a Bristol blue glass ship's decanter.The blowpipe is being held in the glassblower's left hand. The glass is glowing yellow. As a novel glass forming technique created in the middle of the 1st century BC, glassblowing exploited a working property of glass that was previously unknown to glassworkers; inflation, which is the expansion of a molten blob of glass by ...
Scientific glassblowing is a specialty field of lampworking used in industry, science, art and design used in research and production. Scientific glassblowing has been used in chemical, pharmaceutical, electronic and physics research including Galileo's thermometer, Thomas Edison's light bulb, and vacuum tubes used in early radio, TV and computers.
Glass container forming. In the "blow and blow" process, [6] the glass is first blown through a valve in the baffle, forcing it down into the three-piece "ring mould" which is held in the "neckring arm" below the blanks, to form the "finish". The term "finish" describes the details (such as cap sealing surface, screw threads, retaining rib for ...
The bubble is then blown using traditional glassblowing techniques. [6]: 238–239 Cane can also be incorporated in larger blown glass work by picking it up on a bubble of molten clear glass. This technique involves the gaffer creating a bubble from molten clear glass while an assistant heats the pattern of cane.

(Photo by Connor McHugh/PYROSCOPIC) Bob Snodgrass is an American lampworker known for his contributions to the art of glass pipe-making and glass art. He began lampworking in 1971 while learning from and working ...
Soda-lime glass is the traditional mix used in blown furnace glass, and lampworking glass rods were originally hand-drawn from the furnace and allowed to cool for use by lampworkers. Today soda-lime, or "soft" glass is manufactured globally, including Italy, Germany , Czech Republic , China and America .
This glass proved easy to work for glass blowing, and the workshop participants experimented with it in shifts for the remainder of the week. On the final day of the workshop, Harvey Leafgreen, a retired glassblower from the Libbey glass plant in Toledo, happened in to see the public display of the workshop products, and presented an unexpected ...
Glass casting is the process in which glass objects are cast by directing molten glass into a mould where it solidifies. The technique has been used since the 15th century BCE in both Ancient Egypt and Mesopotamia. Modern cast glass is formed by a variety of processes such as kiln casting or casting into sand, graphite or metal moulds.
