Mazurin [1] drew attention to the importance of studying the relationships between the properties and structure of glasses undergoing phase separation. It is evident that viscosity, which is more strongly dependent than any other known property on the composition of glass, must also be the most sensitive to variations of glass structure. Before extensive investigations of the influence of composition of glasses exhibiting immiscibility on their viscosity it is necessary to have a clear idea of the general relationships governing the viscosity of such glasses during heat treatment. The increase of viscosity of sodium borosilicate glasses as the result of heat treatment has been noted earlier [2–4]. However, even investigators who correlated the viscosity variations with heterogeneity of the glasses did not consider the influence of the character of the heterogeneous structure on viscosity.
