A new approach is developed for modeling the temperature and composition dependence of glass viscosity in the system Na₂O-CaO-MgO-Al₂O₃-SiO₂. The temperature dependence is described using the equation log(log h) = A + B log T. The dependence of the coefficients A and B on chemical composition of the glass is expressed using reduced full-cubic mixture polynomials. The new approach is much simpler to develop and use than the previous approach, and it has the potential to yield better property-composition models. The new approach yields an improved model for the dependence of viscosity on composition in the Na₂O-CaO-MgO-Al₂O₃-SiO₂ glass system studied.
