Fused Glass ~ Warm Glass. Fused glass is a term used to describe glass that has been fired in a kiln at a range of high temperatures from 593 C (1100° F) to 816° C (1500°F). The temperature to which the glass is fired determines whether the final product is smooth, dimensional or textured, flat or curved. Warm glass is fused glass. Hot glass is glass that is heated with a torch and blown; cold glass is glass that is “cold-worked” using tools like saws, grinders and polishers. Sometimes cold-worked fused glass pieces can be re-fused into larger pieces or “polished” again in the kiln to make them shiny again.
The precise origins of glass fusing techniques are not known with certainty,
but there is archeological evidence that Egyptians from about 2000 BC were familiar with rudimentary glass fusing techniques, with some controversy over whether 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 and wider practice of glassblowing in the first century due to its greater efficiency and utility of glass-blown pieces. Fusing began to regain popularity in the early part of the 20th century, particularly in the U.S. during the 1960s and especially popular since the introduction of glass manufactured for the specific purpose of fusing in a kiln.
