The Black Copper and Silver Craft is the intangible cultural heritage of Yunnan Province, known as the "Two superb copper crafts" together with Beijing cloisonne. The Black Copper and Silver Craft has a history of more than two hundred years since its formation in the late Qing Dynasty. It can be seen from the study on the traditional Black Copper and Silver Craft that it has achieved the same result as the gilding craft of gold and silver, a traditional metal refining craft in ancient China, by different methods. This paper aims to argue the inheritance relationship between the Black Copper and Silver Craft and the gilding craft of gold and silver from the two aspects of the times and crafts of them. The Black Copper and Silver Craft developed on the basis of the gilding craft of gold and silver, which has produced its own original techniques while combining the advantages of the gilding craft of gold and silver.
