Viscosities of a series of glasses of interest for their bioactivity were determined in the range from 1010dPas up to about 10 dPas. At low temperatures, the viscosities were measured by hot stage microscopy and at high temperatures with a rotational viscometer. Experimental glass compositions within the system Na2O-K2O-MgO-CaO-B2O3-P2O5-SiO2 were chosen statistically to enable statistical analysis of the viscosity data and the development of equations describing the viscosity as a function of glass composition and melting temperature.
