What is the process the glass goes through during fusing?
Based on how much melting the artist wants and how thick the glass is, will determine the temperature of the kiln and the length of time the glass will remain in the kiln. If the glass is not in the kiln for sufficient time, the glass may crack and break from stress left in the glass during the firing process. The kiln can get as hot as 1800, but it usually is used between 1250 and 1600. The glass can be in the kiln from 8 to 12 hours to several days depending on the piece being created. The glass may also go into the kiln more than one time depending on what the artist is creating.
