Glass blowing is a process that involves blowing of molten glass into a bubble which can be sculpted into different forms. Glass cools rapidly & hence needs to be reheated every 30-50 sec.

There are two types of glass blowing techniques:

1. “Blowing glass off-hand” is done using blowpipe. This technique is used to make large sculptures, bowls, vases, plates etc…
2. “Lampworking” is done using blowtorch & mainly used in making glass beads, pendents & small size sculptures.

The glass blowing technique dates back to the first century BC & assumed to be invented in syria. The Roman Empire embraced this technique & experimented to create different shapes & forms. They invented new formulas for color and used gold and silver inlays to decorate vessels. The first enameling techniques came about during this period and were perfected in Egypt and the Middle East. During the middle ages, Venice, Italy became the center of glassmaking as a result of learning the secrets of glassblowing through trade with the Middle East.

The “studio glass movement” began in 1962 when Harvey Littleton, a ceramics professor, and Dominick Labino, a chemist and engineer, started experimenting with melting glass in a small furnace and creating blown glass art in their studio. Thus Littleton and Labino are credited with being the first to make molten glass available to artists working in private studios.
