金铜佛像的鉴定应以类型、轻重、颜色等为切入点，发掘凝固在佛像上的历史痕迹。

The identification of gold and copper Buddha should be based on type, weight and color, and excavate the historical trace of solidification on the statue of Buddha. 

一、类型

Type a, 

中国古代金铜佛像艺术分为汉传佛像艺术和藏传佛像艺术两大部分，要区分风格差异；搞清青铜成分或鎏金等质地；结合时代特征综合判断，以标准器作为真伪依据，判断铜铸佛像是否属于新仿，是否进行过做旧处理。

The art of Chinese ancient gold and bronze Buddha is divided into two parts: the art of buddhist and Tibetan Buddha. To make up the quality of bronze or gilding; Based on the combination of the characteristics of The Times, the criterion is used to judge whether the bronze Buddha statue belongs to the new form and the old treatment is carried out. 

二、 颜色

Second, the color 

古代佛像被放在佛龛上供奉，久历人间烟火，日月侵蚀，特别是鎏金铜造像表层颜色暗淡，在阳光下折射回来的光线柔和。新仿、做旧处理过的铜铸佛像折射光线较刺眼。

Ancient buddhist statues were on niches, and through the earthly fireworks, moon and erosion, especially fine gold copper sculpture surface color dim, refraction back in the sun light is downy. The refraction of the old copper-cast Buddha is a harsh light. 

三、质量

Third, the quality of 

古代佛像所用铜质较纯，质量重，特别是浇铸器物有厚度。仿制金铜佛像一般铜质不纯，质量轻，使用合金材料。

In ancient times, the bronze quality of the ancient Buddha was pure, and the quality was heavy, especially the casting object had thickness. Imitation gold bronze Buddha is not pure copper, the quality is light, use alloy material. 

四、工艺

Four, 

受古老的生产工艺限制，浇铸成型后的佛像要经过细致雕塑技法处理，表情、服饰、底座加工痕迹清晰可见。现代铜铸佛像使用机制打磨，生成极有规律的加工痕迹。

With the limitation of the ancient production process, the sculpture of the Buddha after casting is carefully sculpted, and the marks of expression, clothing and base are clearly visible. The modern bronze Buddha statue has been polished to produce a very regular pattern of processing. 

五、 嗅觉

Five, the sense of smell 

古老的铜质佛像，经长期供奉、烟火熏蒸，可以嗅到烟火味道；倘若长期埋藏于地下，可以嗅到发霉、发朽的味道。而现代仿品嗅到的是化学腐蚀味道。

The ancient bronze buddhas, which are long worshipped and steamed with fireworks, can smell fireworks. If it is buried in the ground for a long time, it can smell mold and rot. And the modern copy smells of chemical corrosion.
