Abstract : The components of the glass were compared as to ionic size and valence and/or position in the periodic table. Modifications in composition included the following ions: Li, Na, K, Mg, Ca, Ba, P, A1, B, and Sn. Silicate glasses were made in the form of standard disks from smelts of a few compositions containing these ions in the oxide form. The compositions were restricted to 2 or 3 oxide systems and were altered by batch additions only. The Na ion was more effective than the Li or K ion in increasing the electrical conductivity in a glass. All of the oxides, with the exception of A12)3 and Sn, tended to decrease the conductivity when substituted in a glass at the expense of SiO2. A12)3 caused a slight increase; Sn, a significant increase.
