History of Fused Glass

     Fused glass consists mainly of silica. While the precise origins of glass
fusing techniques are not known with certainty, there is archeological evidence
that the Egyptians were familiar with rudimentary techniques ca. 2000 BCE. 
Although this date is generally accepted by all researchers, some historians 
argue that the earliest fusing techniques were first developed by the Romans, 
who were much more prolific glassworkers. Fusing was the primary method of 
making small glass objects for approximately 2,000 years, until the development
of the glass blowpipe. 

     While glass working in general enjoyed a revival during the Renaissance, 
fusing was largely ignored during this period as well. Fusing began to regain 
popularity in the early part of the 20th century, particularly in the U.S. 
during the 1960s.
