For the estimation of viscosity of glasses and slags several model equations are generally used, most of which involve three or more empirical constants. The most widely used model for slag systems, proposed by G. Urbain, uses two constants, which are interrelated linearly. Urbain examined data for 54 oxides, silicates and alumino-silicates to establish his model. This paper establishes the validity of Urbain's model for a large number of glasses ranging from binaries, ternaries to more complex systems. The paper also examines the possibility of relating the empirical constants to optical basicity with the ultimate objective of estimation of glass viscosity solely from the composition and optical basicity of the melt.
