Sherds were collected from Hongzhou Kiln covering 8 periods from Eastern Han to Late Tang Dynasty/the Five Dynastied and their bodies were analysed by NAA. The results show that the elemental contents in different samples are quite distinct, even for those in the same period. It means no single element can be used as "fingerprint" to distinguish the period. The curves of the contents of Na, Rb, Ba and Fe varying with lime are very similar, like "U" shape.
