Abstract:Yaozhou ware is one of the most famous ancient porcelains. For non-destructive discrimination of ancient Yaozhou porcelains from different times, chemical compositions of their glaze and body samples are measured by proton induced Xray emission (PIXE), and their PIXE data are statistically treated by dynamic fuzzy cluster analysis. The results indicate that the chemical compositions of Tang Dynasty and the Five Dynasties bodies are much similar, while those of Song and Jin bodies are much similar. The chemical contents of green glazes from Jin dynasty are similar with those from Song Dynasty.
