颜色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。
The color of ancient Buddha statues was placed on the niches for worship. After a long history of fireworks, sun and moon erosion, especially the surface color of gilt bronze statues was dim, and the light reflected back in the sun was soft. The newly imitated and old processed bronze statues of Buddha are more dazzling in refracting light.
工艺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纤维 驱鸟设备 保定通风管道 塑料土工格栅 检查井模具 流水槽模具 锻造厂家 华尔街铜牛制打磨，生成极有规律的加工痕迹。
The technology is limited by the ancient production technology. After casting, the Buddha statues need to be treated with meticulous sculpture techniques, and the traces of expression, clothing and base processing can be seen clearly. The modern bronze Buddha statues are polished by using mechanism to produce very regular processing traces.
嗅觉古老的铜质佛像，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 smell of ancient bronze Buddha can be smelled by long-term worship and fumigation; if buried underground for a long time, the smell of mildew and decay can be smelled. Modern imitations smell chemical corrosion
