景德镇粉彩瓷的EDXRF分析

EDXRF analysis of Jingdezhen famille-rose porcelains

要想客观地完成对粉彩瓷技术史的分析,需要进行相应的测试分析并获得数据支撑。为此,通过景德镇早市购买和收集到的不同时期的粉彩瓷样品,采用美国EDAX公司生产的EagleⅢ型EDXRF测试分析其主次量化学组成,同时借助多元统计分析方法,探讨各时期粉彩瓷化学组成的异同点。讨论结果验证了景德镇粉彩始于康熙,精于雍正,盛于乾隆,而后逐渐衰落的考古学观点,并作出了清三代时期官窑与民窑粉彩配方存在差异,民国时期粉彩颜料发展在前朝基础上有所传承创新,以及早期粉彩中紫彩是由红彩和蓝、绿彩调配而成的推论。

Our study samples,bought and collected at the Jingdezhen Morning Market,were famille-rose porcelains or broken shards of various periods.An EagleⅢ-type energy-dispersive X-ray fluorescence(EDXRF)spectrometer was employed to analyze the primary and secondary chemical compositions of the famille-rose porcelain samples of different periods.In addition,we compared the similarities and differences in their chemical compositions using multivariate statistical analysis methods.The analytical results support the conclusion that Jingdezhen famille-rose porcelains were born in the reign of Kangxi,matured and culminated respectively in the reigns of Yongzheng and Qianlong,but then receded gradually.We also made some inferences:1)the pigment formulas of famille-rose porcelains from imperial and folk kilns were statistically different during the reigns of Kangxi,Yongzheng and Qianlong;2)the famille-rose pigment formula was inherited and also innovated during the Minguo period;3)the purple color of early famille-rose porcelains was mixed with red,blue and green colors.
