The high-temperature resistivity of glass is of great significance to electric glass melting process. The conductive properties of glass at high temperature are measured to provide the necessary technical support for electric glass melting technology. The glass resistivity at high temperature is one of the important parameters for both the all electric glass melting furnace and electrical boosting process. In this paper, three methods for measuring the high temperature resistivity of glass were summarized. They were the direct measurement method of potential probe, the alternating current method and the continuously varying cell constant method. The test principles, advantages and problems of each method were described in detail. It provides a useful reference for measurement of glass resistivity at high temperature.
