This paper evaluates the use of portable x-ray fluorescence (pXRF) on glazes and pastes for sourcing Chinese porcelains from the 12th-13th century Java Sea <i>Shipwreck</i> (JSW) collection at the Field Museum. Three types of <i>qingbai</i> (bluish-white) wares from the <i>JSW</i> collection were chosen for pXRF analysis. Samples from four kiln complexes in ChinaJingdezhen, Dehua, Huajiashan, and Minqing, hypothesized to be potential sources of the shipwrecks qingbai ceramics based on visual inspectionwere 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 <i>JSW,</i> 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.
