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.
