摘要
为保护山东青州香山汉墓出土大量精美的西汉彩绘陶器,针对出土器物的腐蚀病害现状,运用X-射线衍射分析和偏光显微分析等技术手段,对出土彩绘陶器表面的白色盐分产物和陶片本体进行了检测。检测结果表明,表面盐分产物成分为碳酸钙和硫酸钙;该批陶器烧制材料主要由砂屑及粘土构成,所用粘土为岩土矿长期风化的积聚产物;制作工艺以模为主,模、塑结合;并结合以上的几种分析结果对其腐蚀病害及产生机理进行了论述,发现陶器表面风化是云母类矿物内部化学键断裂以及保存环境中的可溶盐的破坏应力所致。本研究结果为彩绘陶器保护修复提供了科学依据。
Large quantities of polychrome pottery were excavated from a Han Dynasty tomb in Xiangshan （Xiang Mountain） , Qingzhou of Shandong Province. To decide how best to preserve these relics, based on their states of deterioration, the white salts on the surfaces and the bodies of the polychrome pottery objects were studied by X - ray diffraction （XRD） and polarized light microscopy （PLM）. These studies showed that the salts are mostly calcium carbonate and calcium sulphate. The body of the polychrome pottery is composed of sand and clay. The clay used is a product of long - term weathering of a clay mineral. The analytical results revealed the production process includes mostly modeling, supported with modeling and sculpturing. The mechanism of deterioration is also discussed based on the results. The surface weathering of the pottery results from the broken chemical bonds within the mica minerals and damage due to the soluble salts from the preservation environment. This research provides important information for conservation and restoration of polychrome pottery.
