/kloc-in the 8th century, the integration of China's chemical knowledge with modern European chemical knowledge is also traceable. As masterpieces of ancient science and technology in China, two works, Heavenly Creations and Compendium of Materia Medica, spread to Europe as early as the18th century and received extensive attention. It was not until the first half of18th century that Europe really mastered China's zinc smelting technology. Han Guoying, Yin and other missionaries in China introduced some chemical knowledge of China to Europe. Two international students from China, Gao Kesi and Yang, studied physics and chemistry in France under physicist brisson and chemist Kadai. In an article commenting on "A Philosophical Study of the Egyptians and China" written by the Dutch philosopher Deborah, Gauguin refuted Deborah's statement that China had chemical knowledge, and thought that China did have alchemy. Han Guoying introduced China's fermentation industry to Europe, such as making vinegar and distilling alcohol from rice wine. He wrote an article about cinnabar and borax in China, pointing out: First, as early as the Tang Dynasty, China artificially synthesized mercury sulfide with mercury and sulfur as raw materials; Secondly, there are records of taking mercury from plants in China's books; Third, borax can be used for welding and purifying metals. He also introduced the glaze technology and steel industry in China. Jin Jishi introduced China's production and chemical technology of alkali, alum, salt, coal, glass, white copper, gold paper and gold lacquer to the west. In addition, at the end of 18, Ji Lan wrote an article entitled "Investigation of Internal Medicine, Surgery and Chemistry in China", which introduced the chemical metallurgical processes such as the extraction of white copper, the preparation of zinc, the iron and steel industry, the production of coke and the preparation of camphor in China.
