宋代西村窑与耀州窑青瓷胎釉化学组成特征

The Elemental Characteristics of Celadon Glaze from Xicun Klin and Yaozhou Kiln in Song Dynasty

利用微聚焦X射线荧光光谱仪对西村窑与耀州窑18件青瓷标本进行原位无损分析检测,结果表明,两个窑口大部分瓷胎中均具有高Al2O3低SiO2的特征;西村窑在瓷胎的主量元素中,具有高K2O低TFe2O3的特征;而在微量元素中,西村窑具有低Cr、Zr、Sr,高Rb的特征;两个窑口的瓷釉中均选用草木灰作为助熔剂,耀州窑的瓷釉均属钙釉,而西村窑瓷釉中既有钙釉也有钙碱釉,同时西村窑瓷釉具有低Sr、高Rb的特征。这些特征将会为西村窑瓷器产地判别提供非常重要的科学依据。

In this paper,18 pieces of celadon samples from Xicun kiln and Yazhou kiln were analyzed in-situ and non-destructively by microfocus-EDXRF.The analysis results indicated that most celadon body from both kilns had the same characteristic of high content of Al2O3 and lower SiO2,but different in microelement content.The celadon body from Xicun kiln had the characteristic of high content of Rb and lower content of Cr,Zr,Sr.The analysis results also indicated that celadon samples from both kilns added the plant ash as the flux in the glaze.And all the glaze from Yaozhou kiln belonged to calcium glaze and some glaze from Xicun kiln belonged to calcium glaze,even though most samples from Xicun kiln belonged to calcium-alkali glaze.And celadon glaze from Xicun kiln had the characteristic of high content of Rb and lower content of Sr.These characteristics could provide an index for discriminating the provenance of celadon from Xicun kiln.
