呢個銅像表面布滿銅綠

當純正或合金狀態嘅銅被腐蝕,銅綠(英文:Verdigris)係會出現嘅幾種淺綠色化合物之統稱。呢啲化合物可以做顏料,叫做青銅色銅綠色。銅綠好多時都係碳酸銅(copper carbonate),如果近海,就可能係氯化銅 (copper chloride)[1]。如果風化過程中間,有醋酸響處(讀似樹)嘅話,就變成醋酸銅(copper(II) acetate)。銅綠個英文Verdigris,係來自中古英文 vertegrez。而之前,就係來自古法文verte grez,即係 vert-de-Grice,就係希臘(Grice)嘅(de)綠(verd)。

醋酸銅夠鮮色,所以係隻好常見嘅顏料。以前啲人見銅綠最鮮,所以就拎來畫畫,所以用到十九世紀都有人用。

銅綠亦都係種藥材
