A Comparison of the Rates of Melting of Some Glasses Made from Sodium Carbonate, Dolomite Limestone and Silica Sand

JSGT 1939 V23 T129-T140

Using the disappearance of batch as a criterion, a comparison of the relative rates of melting of a series of glasses has been made by two methods. Both methods gave substantially the same results. The glasses were made from soda ash, dolomite limestone, and silica sand. The composition range studied was 10 to 18 per cent Na₂O, 8 to 22 per cent (CaO + MgO), and 63 to 80 per cent. SiO₂.
