A bstract Measurements have been made on “stabilized” glass fibers of five compositions in the system soda‐silica, at several temperatures in the annealing range, to obtain the viscosity, Young's modulus for instantaneous and total elasticity, and the. rate of delayed elastic distortion for each glass. Values for the activation energy for viscous flow and delayed elastic distortion have been derived from the temperature coefficients. An ionic theory of the elastic and viscous processes and a discussion of binding energies in the system soda silica are presented.
