The Surface Tension of Glass
JSGT_1937_V21_T053_T060
Two methods have been employed for the determination of the surface tensions of six boric oxide-containing glasses, varying from 0 to 9·05% B2O3• At 1400° the values obtained by the bubble method were approximately twice the values obtained by a fibre method. Increasing B2O3 content of the glasses decreased in a regular manner the surface tension measured by either method. The cause of the discrepancy in the results of the two methods remains uncertain.
