via Journal of Archaeological Science Reports: Portable XRF analysis of Qingbai from the Java Sea Shipwreck.
Forty-one ceramic boxes from the twelfth- or thirteenth-century Java Sea Shipwreck were analyzed at the Elemental Analysis Facility at Chicago’s Field Museum using nondestructive portable x-ray fluorescence (PXRF). Twenty-two samples have a qingbai-type glaze and nineteen are painted ware with painted black decorations originally covered by a lead-based green glaze. The goals of the analysis were to (1) test whether visually similar ceramics shared similar elemental compositions; (2) identify ceramics that might have been made at different kiln sites (or from different paste recipes); and (3) determine if compositional groups in the ceramic dataset differentiated using PXRF are archaeologically meaningful. Based on this study, although PXRF can be successfully used to some degree to differentiate between different groups of qingbai-type ceramics, more research needs to be done on its applicability to painted ware pastes.

Revisiting the date of the Java Sea Shipwreck from Indonesia
In this article we draw on suites of new information to reinterpret the date of the Java Sea Shipwreck. The ship was a Southeast Asian trading vessel carrying a large cargo of Chinese ceramics and iron as well as luxury items from outside of China, such as elephant tusks and resin. Initially the wreck, which was recovered in Indonesia, was placed temporally in the mid- to late 13th century based on a single radiocarbon sample and ceramic styles. We employ new data, including multiple radiocarbon dates and inscriptions found on some of the ceramics, to suggest that an earlier chronological placement be considered.

Java sunken treasure to be sold
Scientists in Indonesia are preparing to auction tens of thousands of artefacts salvaged from a sunken ship off the coast of Java.
The items, which are believed to be more than 1,000 years old, include ceramics, tombstones and swords.
Salvaged after 1,000 years at the bottom of the sea, the haul includes bowls from China, Thailand and Vietnam; perfume bottles from Persia; and swords and tablets engraved with Koranic inscriptions.

Police seize long lost Islamic treasures of the Java Sea
Unique historical treasures worth tens of millions of pounds were yesterday gathering dust in store rooms in Jakarta after being impounded by police.
The 250,000 pieces of Chinese ceramics and Arabic and Persian glassware were recovered from a 1,000-year-old wreck in the Java Sea off Indonesia. Found with them were 13,000 Indian pearls, jewellery, about 1,000 rubies and sapphires and several gold pieces.
