The Influence of Lime on the Value of Young's Modulus of Elasticity for the Lime-soda Glasses

JSGT_1919_V03_T260_T266

As a result of a series of measurements on thirteen different lime-soda glasses of regular variation in composition1 it has been shown that: (1) The regular increase in the amount of lime present causes a continuous and very marked increase in the elasticity of the glass. (2) The conclusions of Winkelmann and Schott, which suggest that lime and soda are but little different in their effects on the elasticity are incorrect. (3) New factors were derived by which it was possible to calculate the elasticity of a simple series of lime-soda glasses.
