Fused and kiln-formed glass sculpture. Fused glass is glass that has been fired (heat-processed) in a kiln at a range of high temperatures from 593 Â°C (1,099 Â°F) to 816 Â°C (1,501 Â°F). There are 3 main distinctions for temperature application and the resulting effect on the glass.
Type Use the correct type of glass. When heating glassware, make sure to use only glassware made of borosilicate glass (PyrexÂ® brand or KimaxÂ® brand). Common glass can break, explode or shatter very easily when subjected to heat shock. Make sure to use test tubes made of borosilicate glass when heating. Not all test tubes are made of borosilicate glass. Proper Use Each type of glassware has its proper use and should be used only for its intended purpose.
