摘　　要：釉里红彩瓷具有十分重要的艺术和科学价值,以往科技研究很少,且尚未见对早期釉里红不同呈色部位化学成分的相关研究。本文采用Micro SR-XRF方法获取了景德镇官窑釉里红瓷器中不同呈色区域的化学成分种类和含量;利用线扫描技术,对深浅颜色变化区域,进行了线扫描分析。结果表明,釉里红彩料中含有As、Pb等元素,不同呈色部位在Cu和As含量上有明显差别。该结果为研究釉里红彩瓷的工艺配方和呈色机理提供了科学依据。Background： The firing techniques of producing underglaze copper red porcelain emerged in the Yuan dynasty and reached its maturity during the Ming and Qing Dynasties in Jingdezhen city. The technique of producing underglaze red porcelain was sensitive to the firing temperature and atmosphere, so it was very hard to produce and also difficult to display red color under the surface successfully. Purpose ＆ Methods： The micro SR-XRF technique was employed to analysis a piece of sherd of underglaze copper red porcelain of early Ming dynasty. The Chemical compositions of glaze and color areas were presented, and the elemental contents in different color areas were obtained by using line-scanning techniques. Results： Some elements such as As and Pb were contained in raw materials, and the content of Cu had obviously increased with the color changing from gray to red. The results indicated that the nature mineral possibly used as the pigment for underglazed copper red porcelain coloration, and the color appearance also depends on the amount of copper in the pigments contained. Conclusions： This paper presents the advantage of the synchrotron radiation XRF technology and contributes to the science evidences for the Chinese ancient porcelain handcraft research.
