The Electrical Behavior of Glass at Room Temperature*

New instruments and equipment are described for the measurement of the electrical conductivity of glass at room temperatures. The accuracy of the method is discussed and certain precautions are specified for this type of measurement. A short review is given of the results of measurements with such equipment on a series of glasses. In particular, experiments are described on the effect of (1) chilling, (2) prolonged heat treatment which produces an actual separation of phases, (3) mechanical strains, and (4) superposed radio‐frequency currents on the conductivity of the glass at room temperature. In conclusion, i t is pointed out that the results of these measurements indicate that the electrical behavior of glass at room temperature is of importance.
