Abstract
In June 2015, excavations in Area E at Swandro uncovered an intriguing fragment of jet-like material that had broken across a hole that had been drilled through it. (The item is Small Find No. 2344, from context 3153.) The item was passed to the author for study and identification of the raw material; it was accordingly subjected to non-destructive compositional analysis by various techniques including particle-induced X-ray emission (PIXE) and X-ray diffraction (XRD) spectroscopy at the Louvre laboratory, Paris, the analyses being undertaken by Dr Lore Troalen (NMS) and Julia Novion Ducassou (an intern student at NMS in 2016) as part of a broader study of jet and jet-like materials.
