A bstract A study of the mechanical strains present in a sample of glass does not insure a prediction of the future behavior of this glass. There is no simple relation between such strains and the physicochemical state of the glass. Most of these states, in fact, probably may be obtained with or without birefringence, depending on the thermal treatment to which the glass was submitted. If the glass is not in the equilibrium condition for the temperature at which it is being used, it will transform spontaneously toward that equilibrium, The birth and evolution of strains depend on these physicochemical unbalances as well as on other characteristics of the glass. Only the study of the physico‐chemical state can give reliable indications of the behavior of glass in practical use.
