The Development of Various Types of Glass. Part IV. The Interaction of Silica, Lime, and the Oxides
JSGT 1920 V04 T059-T070 (12 pages)
The two preceding papers dealt with the interaction of silica and lime first with sodium oxide and secondly with potassium oxide. The present paper deals with glasses containing both the alkaline oxides in conjunction with lime and silica. Thus the “nucleus” of Series I is 100 molecules of SiO2, 20 molecules of Na2O and 20 molecules of K2O, and of Series II, 100 molecules of SiO2, 10 molecules of Na2O and 10 molecules of K2O.
