For multicomponent plate and lead silicate glasses energy of delocalization of atoms Δεe was calculated by experimental data on viscosity. It is shown that size Δεe remains constant in a rather wide range of temperatures in the area of vitrification. The received results are in satisfactory consent with calculation for a formula of model of the delocalized atoms with temperature of vitrification and share of fluctuation volume frozen at this temperature.
