Characterisation of metallic mordants in Subarctic Athapaskan quillwork: a PIXE-RBS study

  title={Characterisation of metallic mordants in Subarctic Athapaskan quillwork: a PIXE-RBS study},
  author={Lore G Troalen and Thomas Calligaro and Claire Pacheco and Alison N. Hulme},
Native American quillwork collections remain little studied due to the limited availability of quillwork material for sampling. In this paper we explore the use of non-invasive Particle Induced X-Ray Emission (PIXE) and Rutherford Backscattering Spectrometry (RBS) to characterise metallic residues in a set of modern porcupine quills prepared with a range of metallic mordants. PIXE analysis was used to determine the concentrations of various mordants present, while RBS analysis allowed…
