Density of Soda-Lime-Magnesia Glasses and Observation on Calculation of Density
JSGT 1922 V06 T228-T231
We have shown in previous papers that whereas, in the trisilicate glasses of general formula 6SiO2.xRO.yNa2O, (where x+y=2) substitution of the soda by lime brings about an increase in density, similar replacement by magnesia produces a specifically lighter glass. The glasses containing the mixed bases lime and magnesia would be expected to have densities intermediate between those containing only the single base.
