金铜佛像辨真伪之看材质：
Material for distinguishing authenticity from falseness of bronze Buddha statues:
金铜佛像有青铜、黄铜、红铜和其它铜合金等，但不同时期的用铜是不一样的，元代以前的铜佛一般都用青铜，也有一些红铜制品，元代以后则出现了较多铜锌合金的黄铜及纯铜制作的所谓红铜佛像，而在青铜上鎏金的佛像一般被称为金铜佛像，黄铜佛像大多是不鎏金的;
Bronze Buddha statues include bronze, brass, bronze and other copper alloys, but the use of copper is different in different periods. Before the Yuan Dynasty, bronze Buddhas generally used bronze, but also some bronze products. After the Yuan Dynasty, there appeared more so-called bronze Buddha statues made of copper-zinc alloy brass and pure copper, while on bronze, gold Buddha statues were added. Generally known as bronze Buddha statues, brass Buddha statues are mostly gold-free;
