An unglazed bottle fired in a Cizao kiln in Jinjiang City, Fujian Province, during the Southern Song. It has a highly narrow bottom and long vessel shape and has a small mouth. This type of bottle was mainly exported to Thailand, Indonesia, Taiwan, etc., along the Maritime Silk Road route. There are various theories about its use, but the view that it was a liquor bottle is currently predominant. It was called the “Ayutthaya jar” in Japan and was prized as a flower vase.

There are no noticeable defects other than the distortion of the vessel shape, and there is no water leakage. It stands by itself but is slightly unstable when using it for flowering.
