The shipwreck Ca Mau is named after the southernmost province of Vietnam, 350 km south of Ho Chi Minh City. The wreck site was first discovered by fishermen in 1998. It is thought that the ship which is a Chinese Djonk was on its way to the Dutch trade entrepot Batavia, nowadays Jakarta, heavily laden with Chinese ceramics intended for the Dutch market. On board were some porcelains with the mark "Yongzheng Period Make" and some bowls marked "Great Qing Yongzheng Period Make". Many pieces still possess many characteristics of the Kangxi period however I feel that pieces from this wreck do more or less precisely dates to the early Yongzheng period.
