材料与造作--唐代的铜材多寡和铸造盛衰

Materials and fabrications:the abundance of copper and the rise and fall of casting in the Tang Dynasty

铜镜等唐代的铜器艺术曾经繁荣,玄宗以后,又渐渐走入衰颓。促成转变的重要原因是铜材的日趋紧缺。在铜镜,主要表现为镜材渐失清纯和镜身转向轻薄,前者使图案的美感普遍下降,后者令图案的艺术手法减少,而图案是铜镜艺术的核心。

The bronze art of the Tang Dynasty such as bronze mirrors once prospered,but after Xuanzong,they gradually fell into decline.An important reason for the transformation is the increasing shortage of copper materials.In bronze mirrors,the main manifestations are the gradual loss of purity and the thinness of the mirror body.The former reduces the aesthetics of the pattern in general,and the latter reduces the artistic techniques of the pattern,and the pattern is the core of the art of the bronze mirror.
