Porcelain occupies a certain proportion in China's export porcelain, most of which are fine porcelain produced in China at that time. It is famous for its gorgeous appearance and typical practicality, attracting attention. Its products are blue and white, multicolored and pastel from Jingdezhen, the most prominent of which is "Guang Cai". The shapes and decorative patterns of many colored porcelains are customized and fired according to the special requirements put forward by European businessmen. As Lan Pu's Jingdezhen Lu Tao in Qing Dynasty said, "There are many Cantonese businessmen who sell to the Japanese market. The style is ingenious and the age is uncertain. " Liu Zifen's "On Bamboo Garden Pottery" in the Qing Dynasty also recorded: "At the beginning of Haitong, western businessmen came to China, first to Macau and then to Guangzhou. In the middle of Qing dynasty, ships gathered and commerce flourished. China businessmen love Chinese porcelain. They burned white porcelain in Jingdezhen, transported it to Guangdong, hired other craftsmen, imitated western paintings, colored it, fired it in Henan on the south bank of the Pearl River, made colored porcelain, and sold it to western businessmen. " Guangzhou porcelain merchants set up a ceramic processing factory on the south bank of the Pearl River. "Tao Ya" records: "The cover was purchased in Jingdezhen, and the painting was processed by the Henan factory in Guangdong, so it was named Cai and He in Henan." These reflect that porcelain merchants at that time mostly bought white glazed porcelain tires from Jingdezhen, Jiangxi, and transported them to Henan processing factory in Guangzhou for painting and low-temperature firing. The products not only meet the special requirements of foreign businessmen, but also reduce the production loss cost.

Because most Guang Cai porcelains are refluxed, many foreigners buy them for decoration, especially large porcelains, so the appearance is good, the display effect is good, and they look magnificent. In recent years, many people began to like collecting Guang Cai. At present, there are many imitations of brilliant porcelain on the market. What I have seen recently are imitation colorful bowls, big bottles and colorful teapots. The difference mainly depends on the age of the painting and the tire bottom.
