This type of single-color opalescent Jun kiln glaze has been found in Linru kilns. The Baofeng Kiln site for porcelain is not far from each other, so the relationship between Jun and Ru is quite intriguing. This kind of single-handled cup is probably the so-called "Qu Xie". It was used in official state banquets in the Southern and Northern Song Dynasties. It was also found in the tombs of high-ranking officials in the Jin Dynasty. It was a drinking vessel. The rim has different widths. The kiln, Longquan kiln, and Ding kiln all made similar shapes; the sunflower petals of this vessel rotate according to the shape, and the glaze color varies with the depth of the concave and convex. It is a beautiful wine set.
