The technique was improved in the Song Dynasty (960-1279), when large quantities of porcelain with red under glaze were produced in Jun kiln inHenan Province. However, the craftsmen's skills were not yet very advanced and there were usually some other colors in the red under glaze.

In theYuan Dynasty(1271-1368), craftsmen began to intentionally make porcelain with red under glaze inJingdezhen,Jiangxi Province, known as the capital of ceramics. In the Yongle Reign of theMing Dynasty(1368-1644), the craftsmanship was very much improved, and the red color became more brilliant.

Later, Jihong porcelain began to be produced for sacrificial ceremonies. Ji means to sacrifice and hong means red. Jihong porcelain produced in Jingdezhen surpassed previous porcelain both in luster and in color. Precious gems like coral, agate,jade, pearls, and gold were sometimes added.
