抄録

A new viscometer, uniform speed penetration viscometer, was constructed with which the viscosity of glass melts can be measured in the range of 10²-10⁸Pa·s. A pin dipped in the melt was penetrated into the melt with a uniform speed and the viscous drag on the pin was measured. A calibration curve between the viscous drag and viscosity was prepared using NBS711 glass as a standard material. The viscosity of glass melt can be determined from the measured viscous drag and the calibration curve. It was ascertained that the viscosities of lead-silicate glasses can be measured by this viscometer in the range of 10²-10⁸Pa·s, and that they agree well with the Littelton point measured by another method. The limits of measurement at high and low viscosities were analyzed and discussed based on the interface phenomena between the pin and the melt.
