Recently an advanced X-ray imaging technique was used on a historic pewter plate linked to the early exploration of Australia by the Dutch in the 17th century. X-ray fluorescence (XRF) has proven to be a highly useful analytical tool for the study of cultural objects, such as works of art and artefacts.
“The non-destructive analysis can provide information about how the objects were made, their composition and insight for conservation strategies,” said XRF beamline scientist Dr Daryl Howard.
“The fast detector on the instrument and its high sensitivity allows us to keep the exposure to radiation to a minimum, which is important for rare and valuable objects. “
In December last year, a small group from the Rijksmuseum in Amsterdam and the Queen Victoria Museum and Art Gallery (QVMAG) in Tasmania brought the Hartog Plate to the Synchrotron for scanning.
