Methods for making glass articles

Abstract:

A method of making a glass article includes melting batch materials to produce molten glass, heating or cooling the molten glass to a temperature, forming a glass article from the molten glass. The batch materials include a plurality of viscosity-affecting components that become at least part of the glass article. Selection of the batch materials or the temperature was made at least in part using computer-implemented modeling where predicted equilibrium viscosity of the glass at the temperature is a function comprising concentrations of viscosity-affecting components and temperature-independent fitting coefficients for the viscosity-affecting components.
