The Density of the Sodium Metasilicate-Silica Glasses

JSGT 1931 V15 T185-T190

The glasses studied in this investigation are with two exceptions identical with those of which the thermal expansions have already been described in an earlier paper.* The glasses were prepared from pure quartz and pure sodium carbonate by melting in platinum, under the conditions described in the earlier work. As other physical properties of these glasses have been in the course of investigation in these laboratories in the past three years, including the electrical conductivity, with the consequent consumption of material, and as the amount of material initially available was never large, it became necessary to make further preparations of the glasses previously described.
