WebSmall induction-heated glass furnaces are used for specialty glasses. The temperature of the glass in the melting section of the furnace is dependent on the composition. For typical commercial glasses, melting temperatures vary from 1500 °C for soda–lime glass to 1600 °C for aluminosilicate glass. WebThe melting process is key to glass quality; and compositions can be modified to change the properties of the finished product.
