Non-destructive pXRF characterisation and authentication of museum ceramics

01st June 2012

This study uses non-destructive portable X-Ray Fluorescence (pXRF) to characterise 47 museum artefacts attributed to Greek and south Italian production of the Archaic Tolate Classical Periods (600-300 BCE). The identification of broad compositional groups for typologically well-understood classes of ceramics is used as a baseline against which to identify and compare the compositional profiles of typologically ambiguous artefacts. Results, interpreted using non-parametric multivariate analysis (Principle Components Analysis), enabled both the re-attribution of typologically misidentified samples as well as the identification of compositional anomalies. The pXRF has also shown new potential for the identification of modern pigments used on reconstructed areas of museum ceramics. Thisstudy demonstrates that non-destructive pXRF offers great potential as a significant new avenue for authentication and compositional research for this class of museum artefact.
