A bstract Using the disappearance of batch as a criterion of melting, a comparison of the rate of melting of twenty‐six soda‐lime‐silica glass compositions has been made. With the composition, Na10 14%, CaO 12%. and SiOt (+R20.) 74%, as abase glass, theeffect of substituting small amounts of B.O., BaO, SOI, etc., on the rate of melting was studied. Theraw materials used were soda ash, calcite limestone. silica sand, dehydrated borax, barytes, salt cake, Chilean saltpeter, ammonium sulfate, fluorspar, and common salt.
