青铜作品有不均匀点状铜锈的情形产生,形成原因通常是青铜作品在环境中受溼度和氧气及二氧化碳的影响形成表面绿色的〝碱性碳酸铜〞，此生成物能防止铜材继续锈蚀，属於无害锈，并无大碍，有些艺术家或收藏家喜欢铜大缸雕塑生成铜绿的质感会刻意保留，但如果您介意这些铜绿生长有碍观赏的话，建议还是交由专业人员来做保养，因为不慎的处理往往会造成作品的伤害。

Bronze works have uneven spot rust, usually due to the influence of humidity and oxygen and carbon dioxide on the surface of the bronze works to form the surface green "alkaline copper carbonate". This product can prevent copper from continuing to rust and is harmless and rust free. Some artists or collectors prefer the Bronze Cylinder sculpture to create a green texture that will be deliberately retained. If you mind that the growth of these aeruginous trees is an obstacle to the viewing, it is recommended to leave it to professional personnel for maintenance, because careless handling often causes harm to the works.
