枣庄市徐楼村红铜铸镶青铜器纹饰镶铸特征

Casting characteristics of copper inlaid bronze unearthed from Xulou Village in Zaozhuang

红铜铸镶青铜器是春秋时期青铜艺术的杰出代表,红铜纹饰的镶铸特征是器物铸造工艺的直接反映,但红铜镶嵌青铜器的制作技术仍有许多问题有待于研究探讨。为此,通过直接观察法和X光成像技术,分析探讨了枣庄市徐楼村红铜铸镶青铜器纹饰镶铸特征。红铜纹饰有与器身基体等壁厚型和非等壁厚型两种。与器身等壁厚红铜铸镶纹饰和器身基体有平口直接镶铸和红铜预留凹槽镶铸两种方式。与器身非等厚红铜铸镶纹饰则利用红铜纹饰在器身浇铸时形成凹槽,红铜纹饰通过与纹饰相连的红铜支钉固定在范芯或在纹饰底部加入垫片方式镶铸于器物基体中。研究成果为红铜铸镶青铜器的工艺过程研究提供材料和证据。

Copper inlaid bronzes were outstanding representatives of bronze art in the Spring and Autumn Period of China. The casting characteristics of the copper ornamentation can reflect the casting technology. Using visual ob- servation and X - ray imaging of the processing details, the casting characteristics of the copper - cast - in - bronzes unearthed from Xulou Village in Zaozhuang City have been investigated. Two types of copper ornamentations have been found. The first type has uniform thickness to vessel body, and second type has non- uniform thickness to vessel body. The uniform thickness copper ornamentations were fixed to the vessel body in two ways： as flat con- nection and grooved connection. The non - uniform thickness copper ornamentations were about half thickness to vessel body, and were also fixed to vessel body in two ways. In the first method, the copper ornamentations fixed to mold core using a copper nail. In the second case, the copper ornamentations were held in the mold using a bronze spacer. After casting, the copper ornamentations were fixed in the bronze body.
