Abstract: In order to reveal the strontium isotope ratios of ancient ceramics unearthed from several kiln sites in North and South China, the elements content and Sr isotope ratios of ceramic samples from 12 kiln sites were tested and analyzed. The results showed: 1) the bodies of North China have the characteristics of high Al₂O₃ and CaO but low SiO₂ and K₂O, while the bodies of South China have higher K₂O and lower CaO; 2) the Sr isotope ratios of ancient ceramic bodies made in different kiln sites show greater variety for the reason that the raw materials used in different kiln sites are from different origins and eras with different Rb and Sr content; 3) the Sr isotope ratios of ancient ceramic bodies made in North and South China have regional difference, the ratios of North China are relatively lower, while the ratios of South China are relatively higher. These regional characteristics are consistent with the research results of chemical compositions.

Key words: ancient ceramic; origin; Sr isotope ratios; chemical compositions
