The viscosity of molten sodium borosilicate system has been measured by a rotating cylinder viscometer, "Rotovisco", using platinum rotor and crucible in a viscosity range from 10^1 to 10^ poise. The obtained results are compared with the viscosity of the glassy state measured previously by a parallel plate viscometer. The following results are derived from the comparison. (1) Fulcher function, logη=A+B/(T-T_0), adequately represents the measured viscosity in the range from 10^1 to 10^ poise. (2) Apparent activation energy of viscous flow varies from 100-200kcal/mol in the glassy state to 20-30kcal/mol in the molten state. (3) Composition dependency of viscosity changes around the composition Na_2O/B_2O_3≅1 both in the glassy and molten sta...
