The Use of Ammonium Sulphate as an Accelerating Agent in Glass Melting.

JSGT_1931_V15_T153_T166

About three years ago, in a paper* having practically the same title as the above, an account was published of investigations carried out in this Department on the effect of three ammonium salts when separately added to the batch in the hope that they would prove to reduce both the melting and the refining time of a soda–lime–silica glass. Such hope, indeed, was shown to have been realised when amounts of these three materials were used in the batch in proportions between 2and 10 parts per 1000 parts of sand employed.
