Evaluation of Firing Temperature of the Bangsan Porcelain
Thermal expansion behavior method in reheating process was used to evaluate firing temperature of white porcelains excavated in Yanggu area,Jangpyung-Ri No.1 (J1,17~20 centuries) and Songhyun-Ri No.5 (S5,14~15 centuries).For standard specimen used for evaluation of the firing temperature,we used starting materials (YC) that have similar chemical composition of J1 and S5 and then they were fired at various temperatures from 800 to 1300℃.Starting temperature of shrinkage and shrinkage rate were measured in thermal expansion behavior in reheating process of the of 1 st fired specimens and the base line for original firing temperature was set based on the results from the measurement of the standard specimens.Effects of particle size of starting materials for standard specimens on the thermal expansion behavior in reheating process were also investigated and the base lines were also set.As a result,we found that difference in particle size for starting materials could cause different shrinkage rate and starting temperature of shrinkage in reheating process even with the same original firing temperature.
