The effect of partial devitrification on the electrical resistivity of three sodium‐bearing glasses has been determined. Resistance measurements were made over a range of temperatures from 130° to approximately 550°C. The resistivity of the glasses studied was found to be influenced by partial devitrification; the nature of this change was found to be proportional to the change in Na 2 O content of the glassy phase remaining after devitrification. The results show that the change in resistivity can be predicted by phase equilibrium diagrams.
