铜在自然界大气中的二氧化硫、碳酸气和水份的长期作用下生成的铜绿--孔雀绿，结构致密、结合强度高，经得起数百年的日晒雨淋。从古代寺庙、文物、工艺品中还能见到。这些铜绿的化学结构是碱式硫酸铜和碱式碳酸铜的混合物。

Copper, produced by the long-term effects of sulfur dioxide, carbonate gas, and water in the natural atmosphere, produces copper green - malachite green. It has a dense structure and high bonding strength, and can withstand hundreds of years of sunlight and rain. It can still be seen from ancient temples, cultural relics, and handicrafts. The chemical structure of these copper greens is a mixture of basic copper sulfate and basic copper carbonate.
