In this paper, I present some of the most recent research taking place on ceramics from the twelfth-to thirteenth-century Java Sea Shipwreck collection housed at the Field Museum of Natural History in Chicago.The cargo was donated to the Museum in 1998/ 1999 by Pacific Sea Resources and includes an estimated 7600 objects, representing a very small proportion of the original cargo.Although the ship itself was probably constructed in Indonesia, it was mainly carrying materials from China——mostly ceramics but also a significant amount of iron.The majority of the ceramics are light-green and light-blue glazed porcelain or stoneware bowls, however, there are also painted bottles and vases, heavily-potted basins and storage jars, and covered boxes with a whitish-blue glaze.Many of the bowls and covered boxes appear to be in the tradition of qingbai-ware, however, they were probably manufactured in Fujian province, near the port of Quanzhou.There are a small number of pieces included in the Museums shipwreck collection that appear to be authentic qingbai made at Jingdezhen.
