many fragments of porcelain and pottery were collected at the site, mostly concentrated in an area of 38 square meters within the reef. among the items recovered were some exquisite blue white porcelain yielded from the jingdezhen factory, in jiangxi province, shadowy blue porcelains, green glazed porcelain plates, pots and other rare antiques. brown-glazed wares have also been found, indicating the possibility that they might be from an even earlier period in time.
