History

The first accounts of glass blowing date back to almost 200 years before Christ. Blown glass arguably enjoyed its greatest popularity during the Italian Renaissance and in early America's Jamestown.
Materials

The glass itself is created when sand, ash and a powdered limestone are heated overnight at 2,300 degrees. When these ingredients melt together, the liquid glass is formed and ready to be blown and formed.

Evaluating Quality
-
Bubbles are common in blown glass, and usually unavoidable. Smooth lips and edges are considered to be the mark of a master craftsman, as is a surface that is free of burns and marks.
Top Artists

Some of the best-known gloss blowers in recent history include Dante Marioni, Marvin Lipofsky and Dale Chihuly--the latter of whom has gained considerable popularity throughout the years.
Warning
-
Glass blowing can be very fun and rewarding, but it takes a tremendous amount of skill and knowledge to master. Taking a class is recommended; it's best to learn the ropes in the presence of a capable instructor.
