The Spectrographic Analysis of Glass-Making Sands

JSGT 1953 V37 T113-T121

Describes a series of experiments to afford information about the following: (1) the best choice of standards; (2) the best internal standards and the most suitable concentrations; (3) the most appropriate line pairs; (4) the types of photographic plates; and (5) the conditions of excitation. The method of analysis which has resulted from the investigation has been in satisfactory use for two years, during which period seven thousand samples have been analysed.
