A bstract The old tedious method of dehydration of silica is replaced by a new, short method. The dehydrating agent used is HClO 4 in place of HCl. The evaporation is performed in a period of 1 to 2 hours by employing a specially designed platinum radiator. The complete chemical analysis of glass is made in a very short time. All ingredients of the glass are determined, one after another, by employing the same sample of the material. The alkali contents are determined by using a separate sample. Many samples of different glasses have been analyzed with satisfactory results, which are tabulated.
