The Song Dynasty marked a peak in the development of Chinese porcelain-making techniques, giving rise to numerous renowned kilns and new varieties. The Jun Kiln in Henan produced famous porcelain with purple-red glaze, particularly a type known as “kiln transformation,” where glazes in red, purple, blue, and white intermingled and permeated one another, creating a radiant and mutually enhancing effect. These pieces are considered treasures among porcelain works. The celadon from the Longquan Kiln in Zhejiang, characterized by its crystalline and emerald green appearance, has been exported to many countries around the world since the Song Dynasty.
