The Use of Ammonium Sulphate in Glass-making

JSGT_1931_V15_T166_T172

That volatile substances present as constituents of a glass batch may under suitable conditions assist in the melting and refining processes has long been known and acted upon. It was realised, however, that it would be advisable to obtain information as to the behaviour of ammonium sulphate when used on plant operating on the full scale. General J. Walker kindly consented to this full-scale experiment being run at the Portland Glass Company's works at Irvine. The problem under investigation was twofold: (1) does ammonium sulphate increase the melting rate?(2) does ammonium sulphate increase the refining rate?It was decided to keep the experimental details as simple as possible in order to obtain definite answers to these two questions.
