An empirical nine‐parameter linear mixing model was developed to estimate the liquidus temperature of zirconia‐bearing technical lithium alumosilicate glasses that contain up to 12 major components. The model covers glasses that are suitable as precursor glasses for β‐quartz or β‐spodumene‐type glass ceramics with low coefficients of thermal expansion. Molar coefficients of liquidus temperatures are provided for each component. A self‐consistency test results in a standard deviation between predicted and measured liquidus temperatures of 7.5°C, within a range of approximately 200°C and for a typical experimental error of 10°C.
