https://www.reference.com/science/melting-point-glass-55c9e756f245e38e
The melting point of glass varies greatly according to what type of glass is being melted, but typically ranges from 2,597 to 2,912 degrees Fahrenheit. The variance in melting temperatures is caused by the mix of materials used initially to create the glass.
