In this paper, we studied the thermal history of a clay core sample from one leg of a bronze tripod unearthed at Daxinzhuang Site, Shandong, China. The properties of the luminescence signals of quartz depend on the maximum temperature at which the quartz was annealed in the past. We ex-amined the feasibility of measuring the thermoluminescence (TL) sensitivity change of quartz for ex-ploring the firing temperature of archaeological materials. The sensitization factor of the 110°C TL peak (S2/S1) and the ratio of the 210°C TL peak to the 110°C TL peak at different annealing tempera-tures were utilized to unveil the firing temperature in the clay core sample. The firing temperature of the clay core sample was approximately 700°C-800°C, proving the clay core has been fired. This re-sult proved that the clay core has been fired by human agencies and indicated on the temperature of the clay core in drying and firing given by the foundry workers before the actual casting step.
