The Determination of Iron in Glass

JSGT 1936 V20 T303-T314

Calorimetric, gravimetric, volumetric-oxidation, electrometric and volumetric-reduction methods are described for the determination of the total iron content of glasses. For the determination of ferrous oxide a modification of J. H. Pratt's hydrofluoric acid method is found to be the most reliable: The improvement of the method resulting from a systematic examination of the factors affecting its accuracy is described.
