Antique Vietnamese annamese porcelain stoneware pear-shaped water dropper.

Decorated with traditional symbols using grey-blue cobalt underglaze, including butterflies and lotus flowers.

These items were a scholarly object, and historically used for diluting a cake of ink (on an inkstone) to obtain the preferred consistency for use in calligraphy or painting.

This and other molded water droppers were recovered from the famous Hoi An shipwreck cargo, discovered in the 1990s. Total intact porcelain artifacts recovered numbered above 250,000. Pieces unique to the cargo were kept by the Vietnam government, with the remainder auctioned by Butterfields in San Francisco in 2000.
