The features of the effect of the composition and structure of glasses of the systems Na2O – CaO – B2O3 – SiO2 and Na2O – CaO – B2O3 – Al2O3 – SiO2 on the temperature curve of the viscosity in the 1010 – 104 Pa · sec range were established. The important effect of phase separation processes—liquation and crystallization—on the viscosity indexes in the temperature region of the transition from the plastic to the liquid state was demonstrated.
