Abstract
A model for estimation of viscosities of glass melts at relatively high temperatures has been previously reported from this laboratory in this journal (see text). This paper describes an approach for extension of the model to relatively low temperatures. In addition, another novel method for estimation of viscosity over a wide temperature range is presented. Viscosity data on several commercially important glasses are reported to discuss the applicability of these models, all of which employ Optical Basicity (OB) of the system as a compositional parameter.
