Conventional flat glass compositions are melted in a continuous melting process with lowered sulfur-containing emissions and with improved fining at high batch-to-cullet ratios by controlling the amount of SO3 included in the batch materials and cullet. This is accomplished while maintaining high throughputs and without using substitute fining agents. Preferably, the amount of carbon in the batch is maintained at a minimal level or eliminated.
