1 This standard was originally published in 1979. The first revision has been undertaken to bring it in line with the technological changes that may have happened over the last four decades. Several editorial changes such as the inclusion of the ICS No., Hindi Title, Reference Clause, etc. have also been incorporated.
2 Sodium nitrate and potassium nitrate are used in batch compositions of glass, enamel frits and glazes in which their chief function is to oxidize organic matter which may contaminate batch materials, prevent reduction of some of the batch constituents, help maintain colours and accelerate the melting and fining processes.
