A bstract It is shown by measurements on samples of glasses having a varied degree of heat treatment that the electrical conductivity of glasses undergoes a stabilization process at constant temperature and that this rate of stabilization is a function of the viscosity of the glass. The resistance of the stabilized glass varies linearly with 1/ T , where T is the absolute temperature, and no change in the slope of this curve is observed. In other words, there is no transformation point observable when all measurements are made on stabilized glass.
