Abstract—An improved experimental technique of investigating the mechanical relaxation in inorganic
glasses is described. The temperature and concentration dependences of the stress relaxation times and their
spectra are analyzed for commercial glasses. It is demonstrated that the results obtained make it possible to sim-
ulate stresses in glasses and their seals with other materials, including other glasses. The kinetics of stress relax-
ation in commercial sheet glasses is examined. It is emphasized that the results obtained can be affected by the
composition of the gas mixture used for preparing samples in the flame of a burner.
