Various Na 2 SO 4 ‐Na 2 CO 3 ‐CaCO 3 ‐SiO 2 combinations were studied by differential thermal analysis to elucidute the role of Na 2 SO 4 in soda‐lime‐silica glassmelting reactions. It was found that Na 2 SO 4 encourages the formation of wollastonite at 850° to 900°C. The solid‐state reaction of Na 2 Ca(CO 3 ) 2 occurs very readily at temperatures in the vicinity of 400°C. The Na 2 Ca(CO 3 ) 2 must therefore be considered a major constituent in glass batches containing both soda ash and limestone .
