辽宁一些清代建筑琉璃构件釉面有轻微的乳浊感,能量色散X射线荧光谱仪(EDXRF)测试结果表明釉料中含有锡元素,氧化锡含量最高可达3.67%;在扫描电镜(SEM-EDS)下观察到釉层中存在大量富含锡的晶体颗粒,其大小一般小于1μm;激光拉曼光谱(Raman)分析表明锡在釉中以氧化锡物相存在,未见铅锡黄物相。本文在实验分析的基础上结合文献记载,对辽宁清代琉璃乳浊釉中氧化锡的功能和来源进行了初步的探讨。
Some glaze of some glazed glazed elements in Qing Dynasty in Liaoning Province had slight opacity. The energy dispersive X-ray fluorescence spectrometry (EDXRF) test showed that the glaze contained tin and the content of tin oxide was up to 3.67%. SEM- EDS) observed a large number of crystal particles in the glaze layer is rich in tin, its size is generally less than 1μm; laser Raman spectroscopy (Raman) analysis shows that the tin in the glaze to tin oxide phase exists, no lead tin yellow phase . Based on the experimental analysis and the literature records, this paper discussed the functions and sources of tin oxide in the glazed opaque glaze of Qing Dynasty in Liaoning Province.
