Abstract

Abstract: This paper evaluates the use of portable x-ray fluorescence (pXRF) on glazes and pastes for sourcing Chinese porcelains from the 12 th -13 th century Java Sea Shipwreck (JSW) collection at the Field Museum. Three types of qingbai (bluish-white) wares from the JSW collection were chosen for pXRF analysis. Samples from four kiln complexes in China—Jingdezhen, Dehua, Huajiashan, and Minqing, hypothesized to be potential sources of the shipwreck's qingbai ceramics based on visual inspection—were also analyzed to establish reference groups. Results from kiln samples show that different kiln complexes can be clearly differentiated by pXRF analysis of glazes. Based on pXRF analysis of ceramic samples from the JSW, there appear to be four compositional groups, and each group closely matches one of the four kiln reference groups. These findings support the use of pXRF on glazes, especially when pastes are difficult to access, as a method for identifying the potential sources for overseas cargos found distant from production contexts for Chinese porcelains. Highlights: pXRF can discriminate qingbai porcelains from different kiln complexes in China. pXRF on glazes is effective to source Chinese porcelains. Java Sea Shipwreckqingbai porcelains came from four different kiln complexes in China.
