Abstract The effects of refining time on the transformation temperature, viscosity, and rate of crystallization of a simple lead phosphate glass of nominal composition 60 P2O5, 30 PbO, 10 K2O have been determined. As the hydroxyl content is reduced and the cross-link density increased by continued refining, the transformation temperature and melt viscosity rise. At corresponding temperatures above T g the viscosity increases and the rate of crystallization decreases with cross-link density, but crystallization rates at isoviscous temperatures are shown to be independent of cross-link density.
