Abstract
The Indian Standard method for testing alkalinity of glass was modified to improve the accuracy and raprdity of the m.ethod. Ten commercial glasses having widely different chemical durabilities were tested for alkalinity· and the extracted amounts of alkalies were estimated flam!] photometrically as well as by titration. The results obtained by the two methods show that the extracted glass conftituents other than the a~~alies did not have any effect on the titre value. The same sample~ were also tested according t.o the DIN method as proposed by the International Standards Orgarl!isation and the ratio of the titre values as obtained by the !._S and D!l:L methods was found to be 0.55.
