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.
