Equations to calculate the room temperature density of fused SiO_2-MnO-CaF_2 fluxes from their chemical composition were derived. Firstly, the equation based on the additive law was examined using density factors examined in the preceding paper. For calculation, the chemical composition of the fluxes and the actual density measured by an air picnometer were put into the additive equation with f_<CaF_2> as an unknown quantity. Thus the density factor for CaF_2 was determined as 2.97. Secondly, the multiple regression equation was applied. In this case, the actual density and the chemical composition were treated by a computer to obtain the regression coefficients and the constants. Consequently, the deviation range of the calculated density from the actual one was found to be ±0.05 g/cm^3 both for the additive equation and -0.04〜+0.03 g/cm^3 for the multiple regression equation.
