The Development of Various Types of Glass. Part II. The Interaction of Silica, Lime and Sodium Oxide
JSGT 1920 V04 T020-T045(26 pages)
The majority of the commercial glasses in use at the present time are manufactured by the interaction of silica and the oxides of sodium and calcium at high temperatures. The fact that lime confers special properties, of durability upon glass containing it has been known from the early days of glass manufacture. It was natural, therefore, to make the investigation of the influence of calcium oxide upon the oxide of sodium and silica the next step in the development of types of glass. Two series of melts were carried out according to the scheme. The basis or nucleus of the first series is the glass 100SiO2.40Na2O. The "nucleus" of the second series is the glass 100SiO2.20Na2O.
