Basic Introduction to Wujin Paper

Wujin paper is a specially made black and glossy paper. Commonly used for mounting or packaging, it is an important tool in the production process of precious metals such as gold. Wujin paper has a long history. In the late Ming and early Qing dynasties, a person named Wei Liangzai invented it. Originally called "smoked gold paper", it was later called "black gold paper" and could only be made in Shangyu, Zhejiang. Therefore, there was a saying at that time that "black gold paper exists in all parts of Zhejiang"

Black gold paper is mainly used for padding in the production of gold, silver, and aluminum foil. The gold, silver, and aluminum foil produced by sandwiching (padding) black gold paper is used as a manufacturing trademark by many factories. Songxia Wujin paper has the characteristics of being both tough and thin, with even ink without patches, and a shiny black color, so it has always been favored by the manufacturing industry both inside and outside the province, and even abroad

How did the history of black gold paper come about

In the book "Tian Gong Kai Wu: Gold" by the Ming Dynasty scholar Song Yingxing, it is recorded that "all black gold paper was made in Suzhou and Hangzhou. The paper was made of East China Sea giant bamboo film. It was lit with soybean oil, sealed with air to prevent pinholes from passing through, and smoked with smoke. Each piece of paper was coated with gold foil at fifty degrees and then discarded for use in medicine shops. It was not damaged and was covered with human ingenuity, causing foreign objects." The production of black gold paper requires multiple processes such as material selection, paper making, paper cutting, pressing, smoking, ink coating, baking, trimming, issuing, and packaging. In the 1840s, Zhu Zhaoyan, who was engaged in the production of black gold paper, moved back to his hometown of Cailin in Songxia from Shimen Town, Tongxiang County (now Tongxiang City) and started a black gold paper family workshop for survival. After the establishment of the People's Republic of China, the town of Songxia gradually developed and grew by recruiting relatives and neighbors as workers, teaching through words and deeds. As a result, the manufacturing industry of Wujin paper emerged in Songxia Town. After gradually weakening, the intangible cultural heritage was surveyed and re excavated and organized
