The energy dispersive X-ray fluorescence (EDXRF) is used to determine thechemical composition of celadon body and glaze in Longquan kiln (at DayaoCounty) and Jingdezhen kiln. Forty typical shards in four cultural eras wereselected to investigate the raw materials and firing technology. Randomforests, a relatively new statistical technique, has been adopted to identifychemical elements that are strongest explanatory variables to classify samplesinto defferent cultural eras and kilns. The results indicated that the contentsof Na2O, Fe2O3, TiO2, SiO2 and CaO vary in celadon bodies from Longquan andJingdezhen, which implies that local clay was used to manufacture celadonbodies in Jingdezhen kiln. By comparing the chemical composition in glaze, wefind that the chemical elements and firing technology of Jingdezhen kiln arevery similar to those in Longquan kiln, especially for Ming dynasty. This studyreveals the inheritance between Jingdezhen kiln and Longquan kiln, and explainsthe differences between those two kilns.
