A technique unique to glass, air twist requires very high quality material for success. When sparkling lead crystal became common in 18th-century England, the air twist technique spread rapidly.
By about AD 20, Roman workers had discovered that a bubble of molten glass could be lowered into a mold and then further inflated to fill the mold. In this way, the full-size vessel, complete with elaborate decoration, was made almost instantly.
Molten glass can be cast by a method virtually identical to that used for casting metal. Here, molten glass at 2300 degrees Fahrenheit is ladled into a mold made of sand. The process is relatively easy as hot glassworking processes go...but hot!
Don't try this at home! A classic demonstration involving exploding glass: it spectacularly shows both the great strength and vulnerability of glass that has been rapidly cooled from the molten state.
While glass canes can be used alone, for example as stirring rods, usually they are incorporated in vessels or sculpture. An infinite variety of decoration is possible. Here we see two examples that are intended to be viewed from the side.
Here is virtuoso Venetian-style glassblowing "without a net." One mistake and all is lost! Where "making a goblet from parts" allows mistakes to be isolated and destroyed, this process moves relentlessly forward, allowing no retakes.
Popular among glass artists today, as it was in the golden age of Greece and the Roman Empire, this technique softens and shapes glass in a kiln. Various preparatory steps are shown in the making of a contemporary sculpture.
It could have been so simple...but it wasn't! Until recent times (about 1800), permanent enamels had to be fired on glass vessels by an amazingly laborious process, shown here. Today, the process really is as easy as it looks.
Five different methods of using colored glass are demonstrated; some produce a uniformly colored object, others a splotchy or mottled effect. Glass artists today use whatever method best suits their aesthetic choices.
Roman glassworkers, tirelessly creative and inventive, were fond of folding and manipulating inflated glass in a variety of ways for different purposes. Two of their characteristic structures—both functional and beautiful—are demonstrated.
As if glassblowing wasn't fast enough—it takes under three minutes to make a Roman bottle—cracking-off made the process even faster. This technique was well known by AD 20 or so, and cut the manufacturing time of simple tumblers in half.
Chunks of glass are placed in a mold, then heated in a kiln until the glass softens and flows downward to gradually fill the mold. Popular with contemporary artists, this method avoids the need for a giant melting furnace filled with molten glass.
Cutting thin sheet glass is almost as easy as it looks in this video clip...but not quite! Curves really are much trickier than straight lines. The process shown would have been completely familiar to medieval window glaziers.

Designer Tom Scott describes working at GlassLab during a design session at The Corning Museum of Glass, July 24- 25, 2012.
Anne Gant is one of the few glass artists to work on paper. Watch as she uses hot glass to make prints and drawings in a fascinating combination of glassblowing and printing or drawing with glass. First, two glassmakers sculpt hot glass into shapes and lines. While the glass is still scorching hot
"I want the viewer to expereince the process of blurring boundaries between cultures by looking at my work." Song studies ornamental styles across time periods and geography, and her work explores how certain attributes of glass can be used to create ambivalent objects: objects that don&
Gayla Lee was first entranced by glass at the age of eight when she encountered a glassblower at a Renaissance festival. Her fascination with the material eventually led her to an apprenticeship in a Baltimore glass studio at the age of 20. Lee took Davide Salvadore's class, Creating and Using

Tobias Wong at GlassLab at the Cooper-Hewitt, National Design Museum, May 17-June 3, 2008. A program of The Corning Museum of Glass, GlassLab brings designers together with glassmakers to offer them rare access to experimenting with hot glass and prototyping their design concepts.
Philadelphia-based artist Christopher Lydon makes organically inspired sculptural and vessel forms as well as works with intense color contrasts that reference street art and anime. At 2300°: Blues in March 2012, he made a glass guitar modeled on BB King's signature guitar, Lucille.
Norwood Viviano uses digital 3D modeling and printing technology in combination with the casting process to create his sculptural works. In his March 2012 Residency at The Studio, Viviano plans to create urban and/or industrial landscapes out of kiln-cast glass as an extension of his previous
