X-ray advances Aboriginal culture study

Written for Chemistry World by Sarah Rogers

Graphical Abstract

For the first time, Australian scientists have studied complex mixtures of natural pigments on intact Aboriginal Australian artefacts using x-ray fluorescence microscopy.

Previously applied to canvas paintings, the group at Flinders University applied the technique, which analyses the composition, application and layering of pigments, to two indigenous Australian objects – a boomerang and a bark painting. X-ray fluorescence microscopy allows complex elemental analysis of pigment mixtures of varying thickness without the need for damaging sample extraction. The objects are analysed directly in the x-ray beam.
