2. The silver circulating in the market can be roughly divided into the following categories: Qianzuyin, Zuyin, 925 pure silver, 18KGP/ 18KRGP, marcasite, Tibetan silver and Miao Yin. Qianzuyin: refers to silver with a silver content of 99.9%, and Zuyin: refers to silver with a silver content of 99%. Miao Yin: Miao silver is not pure silver, it is a kind of silver metal unique to Miao people. Its contents include silver, copper, nickel, etc. The contents in Miao Yin are different, ranging from 20% to 60%. The so-called 99.9% pure Miao Yin is basically a lie, and occasionally the silver made by the real old Miao people is at most 90%. The purity of 99.9% can't be refined by traditional technology.
