Abstract: A total of 28 old Jun porcelain, seven modern Chinese Jun porcelain and two Jingdezhen porcelain samples are analyzed with INAA method. The systematic geochemical study for these 37 samples on their REE and trace elements shows that these three types of china were made with relatively stable and similar material, although they leaptover 600 years in different colors and from different kilns. However, the REE patterns of modern Chinese Jun porcelain are a little bit different from that of old Jun porcelain, and clear different from the old glaze of Jindezheng.
