ItemA preliminary comparative technical analysis of earth-based pigments used by Aboriginal artists from the Kimberley region and other natural, synthetic or commercial sources(International Council of Museums, 2014)Developing non-destructive analytical methodologies for Indigenous Australian cultural heritage is of critical interest for art historians, curators, artists and conservators. Prompted by an observed increase in the number of Australian Aboriginal artworks with problematic provenance, highlighted in a ground-breaking authentication case, and technical questions raised by the need to treat flood damaged artworks, research was undertaken to determine the best methods for analysing ochrebased paints. As many Aboriginal paintings and artefacts are predominantly composed of earthbased pigments, samples of synthetic pigments and naturally occurring ochres were obtained from a range of commercial and geographic sources, including Australia’s East Kimberley region. A combined methodology based on particle induced xray emission (PIXE), Australian Synchrotron powder diffraction (AS-PD) and microscopy was developed to explore the ability of a complementary data set to differentiate between synthetic and natural earth-based pigments from Australian and overseas sources. In addition, such investigations will ultimately be used to generate a database of elemental, mineralogical and microscopy data with the aim of establishing provenance and informing conservation treatment approaches.
