Abstract:
      A lot of beautifully crafted brassware, strongly influenced by Islamic design, has been recovered from the No.1 shipwreck in Northwest Continental Slope of the South China Sea. Metallurgical analysis, alloy composition assessments, and trace element analyses were performed on the recovered bronze vessels. The results show that the shaping method of the copper wares from the shipwreck is mainly forging, the thin-walled wares account for a large proportion of the wares, with a high level of manufacturing, and all the alloy materials are brass. Based on the analysis of the technology and characteristics of the raw materials, this batch of copper wares is likely made from mined brass, probably sourced from the southern region. The concentration of zinc and the low presence of sulfide inclusions suggest that the craftsmen possessed relatively advanced techniques for alloying mined materials.
