This celadon bottle was made in the Longquan (龍泉) kilns in Zhejiang Province, China. It was excavated from the site of a shipwreck that is estimated to have occurred sometime in the early 14th century near Sinan in a cluster of small islands in southwest Korea. More than 30,000 artifacts were recovered from the site, which is known to have been a single merchant vessel sailing from China to Japan. The recovered items include personal belongings from the passengers and crew of the ship, as well as the ship’s commercial cargo largely consisting of earthenware and ceramics, much of it produced at the Longquan kilns. Thus, the Sinan shipwreck artifacts provide a fascinating in-depth look at the lifestyle of the period. This bottle is coated with a soft, light glaze that causes it to appear almost like a piece of green jade. The distinctive color is indicative of ceramics produced at the Longquan kilns during their peak. In addition, the refined shape modeled after bronzeware exemplifies the elegance of ceramics used in the Song Dynasty royal palace.
