We developed in the previous report a simple and low-cost method of measuring thermophysical properties of ceramic materials by stepwise heating. One of the important points in the method was the method of measuring the surface temperature of a specimen in a simple and low-cost manner : the surface-temperature was measured by pressing separated thermocouple wires against the specimen surface to which an aluminum foil was attached to create high electric and thermal conductivities. However, the optimum conditions of the thicknesses of the aluminum foil and the thermocouple wire were not evident in the previous report. In this report the effects of these parameters on the accuracy of the measurement have been investigated theoretically and experimentally by using Pyrex 7740 glass as a specimen, and the optimum conditions of the measurement have been clarified.
