以南京大报恩寺遗址出土的典型明代琉璃样品为研究对象，通过能谱扫描电子显微镜、X射线衍射仪和 X射线光电子能谱仪等进行古琉璃釉面腐蚀的显微特征、腐蚀产物成分、物相结构以及琉璃胎釉结合层的显微分析等，结合样品埋藏所处的环境分析，探索典型琉璃样品表面的腐蚀机理。研究表明古代建筑琉璃构件的含铅釉面在埋藏土壤环境中化学稳定性较差，不同颜色釉面发生不同程度的腐蚀，腐蚀产物分别为含铅/钙的磷酸盐络合物、不同晶形的磷酸铅盐或碳酸铅；含Ca、P元素的釉面腐蚀较为严重，从釉层表面腐蚀直至内部胎釉结合处；推断腐蚀产物除了受铅釉釉层的化学组成、表面结构影响外，还与土壤水膜、pH 和土壤胶体颗粒中的离子交换等因素有关，该研究为琉璃文物的腐蚀机理研究和保护提供了科学依据。

The microstructure,morphology and composition of the main deterioration products of the glaze layer,as well as the interface between glaze and body in the representative glazed tiles excavated from the site of Bao’en temple in Nanjing had been tested by scanning electron microscopy with an energy dispersive spectrometer,X-ray photoelectron spectroscopy and X-ray diffractometer.The surrounding soil properties of the glazed samples had also been analyzed and the corrosion mechanism of the typical samples had been explored.The results show the corrosion of glaze layer has a direct relationship with the composition of glaze layer,which is mainly composed of the lead oxides,and the different degree of corrosion and the lead/calcium phosphate complex,as well as the crystalline of lead phosphorylate and lead carbonate had been analyzed respectively in the different color glaze layers.The changes of chemical composition and surface structure in glaze layer are related to the water membrane,pH,ion exchange and adsorption,as well as the soil colloidal particles in the soil.The analysis of the main deterioration of glazed tiles excavated from the site of Bao’en temple in Nanjing provides effective information for preserving the deteriorated products and the subsequently relevant protection.
