Northern Song Dynasty Jun ware Celadon Bowl with Board Edge Design

Jun ware celadon bowl made in the Northern Song dynasty.
It can also be considered as ru ware from the structure of the vessel and the state of the bottom.
It has a wide mouth and a rounded shape, with one side of the mouth rim serving as a petal fold and a ring-shaped handle below the rim.
This style became popular in the Song and Jin dynasties, mainly in the kiln.
Jun ware's unique devitrification and whitish celadon glaze is reminiscent of Northern Song Ru ware.
The base is slightly recessed, three nail marks are left, and the entire surface is glazed.
Noteworthy is the character "Cai" engraved on the bottom, which is attached to porcelain made for the Cai family, who collected porcelain during the Northern Song Dynasty.
The Cai family refers to Cai Jing, the chancellor of Emperor Huizong of the Northern Song Dynasty, and his son.
It is said that he owned many high-quality ceramics made mainly by Ruware.
Therefore, this item has the potential to be ru ware, not jun ware, due to the similarity of the above points, glaze, and bottom.

There is soil coloring. The glaze at the tip of the edge flower is peeling off a little.There is aged deterioration on the entire surface, but there is some luster.
