[Study on the cultural relic material site and period by EDXRF]

With the development of the element analysis technology, the energy-dispersive X-ray fluorescence (EDXRF) technique is now well established as a powerful tool for qualitative and quantitative elements analyses when studying on the cultural relic materials. Being characteristic of quick and non-destructive analysis, involving high-precision, a wide concentration range, easy sample preparation, good reproducibility and synchronously analyzing the elements from Na(Z11) to U(Z92), this technique is appropriate for analyzing precious ancient ceramics. In the present study, the major, minor and trace elements compositions of 6 samples from Guan kiln in the southern song dynasty, 6 samples from Longquan kiln in the Southern Song dynasty and 2 modern imitations were analyzed by EDXRF. The results prove further that the raw materials in Hangzhou and Longquan are different and stable, and show that EDXRF is a successful and feasible method for identifying the provenance and dynasty an ancient ceramic originated from.
