ABSTRACT
The successful study of momentum (viscous flow), energy (heat conduction, convection, radiation), and mass transport (diffusion, chemical kinetics) in molten glass processes is dependent upon the accuracy of the scientific assumptions and physical properties used to describe these phenomena. All three areas have a long history of development in the chemical industry and the associated mathematical equations are well posed. The difficulty comes when these equations are applied to molten glass where the critical physical and chemical properties are unknown. This problem arises
ranges of operating conditions and parametric studies. In some cases, property information is so deficient that educated guesses have been used that later are shown to be completely incorrect.
