Jun glaze - the color glaze of Jun porcelain. The main shapes of Song Dynasty Jun porcelain include washing vessels, plates, incense burners, bowls, and tripods. Among these, the bottom of those selected for imperial court use often has a number from one to ten carved into it, representing the size of the vessel. There are two types of inscriptions on the body: "Fenghua" and "Shengfu". Generally, in Jun porcelain production, the porcelain body is first fired plain, then glazed, and finally fired at high temperatures under a reducing atmosphere. -- Golden Horse Lotus
