Abstract

We propose a novel noncontact method for measuring the viscosity of high-temperature glass melt using a smallamount of sample. This method combines the electric-field tweezers system developed for measuring the local anddynamic surface properties of soft condensed materials and the hot-thermocouple technique for in situ observation andmeasurement of high-temperature liquids. The viscosity of B₂O₃ melt was measured in the temperature range of 873to 1473 K. The temperature dependence of the viscosity presented in this work is in reasonable agreement with thatreported in the references.
