All About Glass | Corning Museum of Glass

Formers make up the largest percentage of the mixture to be melted. In typical soda-lime-silica glass the former is silica (Silicon dioxide) in the form of sand. Fluxes lower the temperature at which the formers will melt. Soda (Sodium carbonate) and Potash (Potassium carbonate), both alkalis, are common fluxes.
