A great number of porcelains and some metalwares of the middle and late Tang Dynasty were archaeologically salvaged from the Batu Hitam shipwreck, providing important material evidence for the Maritime Silk Road. Through interpretation of the shapes, decorations and patterns of Changsha Kiln porcelains, Yue Kiln celadons, white porcelains, famille verte, gold and silver wares and bronze mirrors, the general conditions and cultural exchanges involved in export porcelains of the middle and late Tang Dynasty are illustrated, and the influences of export on parts of kilns in China are analyzed. The possible provenances of export white porcelains are also discussed according to the elemental composition analyses of two samples using X-ray fluorescence (XRF) spectrometry. This paper also discusses the possible departure and destination ports of the ship.
