Further Investigations of the Influence of Alumina on the Properties of Glass

JSGT 1924 V08 T173-T181

 It was of considerable interest to extend the observations on alumina in glasses by a study of glasses analogous in composition to the boric oxide glasses, that is, to glasses in which silica is progressively replaced by alumina weight for weight. The results with the two previous series of glasses tested had given no indication of abnormality, such as is exhibited by the boric oxide glasses, but a strict comparison could not be said to have been made.
