A famous kiln in the history of China was named after Longquan, its main producing area. It started in the Three Kingdoms and the Jin Dynasty and ended in the Qing Dynasty. It has a history of 1600 years. This is the longest porcelain kiln system in the history of porcelain making in China. Its products sell well in many countries and regions in Asia, Africa and Europe, with far-reaching influence.

The glaze color of Longquan kiln is turquoise, mostly pink blue in the Northern Song Dynasty and onion blue in the Southern Song Dynasty. If you don't open the piece at the turning point of the vessel, it often presents fetal color, and the porcelain glaze is thick and moist, and there are few carvings and scratches on the decoration. However, decals and reliefs are more popular. For example, plates are often piled with Pisces patterns, and bottles are covered with peony patterns.

The porcelain industry reached its peak in the Song Dynasty. Besides the five famous kilns mentioned above, Pingyang Kiln in Pingyang, Shanxi, Yaozhou Kiln in Yaozhou, Shaanxi, Jian 'an Kiln in Fujian and Jizhou Kiln in Jizhou, Jiangxi also produced quite good porcelain.

Cizhou Kiln, located in today's Cixian County, Hebei Province, is the center of large kiln industry in northern China, which is highly valued by Japanese. A large number of porcelains have been sold to Japan in the past dynasties, and there is a reason why the Japanese also call porcelain porcelain.

In the Southern Song Dynasty, two brothers, Shengyi Zhang and Zhang Sheng, set up a kiln factory in Longquan, and the raw kiln was named "Ryukyu Kiln", also known as "Ge Kiln"; The kiln that holds the second burning is called Longquan kiln, also called underground kiln.
