Abstract: An extended interpretation of the Wolkenstein–Ptitsyn formula for temperature band $\delta T_g$, characterizing a range of transition from liquid to glass, is considered using the Razumovskaya–Bartenev concept. The derivation of this formula proposed by the authors does not depend on the specific type of temperature dependence of relaxation time. For silicate glasses, calculation $\delta T_g$ by this formula agrees with the calculation by the Williams–Landel–Ferry relation and with the left side of glass transition equation $q\tau_g = \delta T_ g$, where $q$ is the cooling rate and $\tau_ g$ is relaxation time. Based on the experimental data, the calculation of parameters of the Razumovskaya–Bartenev equation for silicate glasses and amorphous polymers is carried out for the first time.
