The Effect of Changes of Composition on Density Changes in Silicate Glasses
JSGT 1946 V30 T327-T332
Approximate equations, published by L. G. Ghering and M. A. Knight and by R. M. Elliott, for the calculation of the change in density of a glass resulting from small changes in composition are discussed. The corresponding more exact equations, deduced from fundamental relationships previously published and tested by the authors, are presented. They are only slightly more complex than the approximate equations and do not require the preparation of a new table of constants for the density of each new base glass.
