Chemical Analysis of Two Ancient Roman Curse Tablets

Two different Roman curse tablets have been analyzed using standard analytical techniques including X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Energy dispersive x-ray spectroscopy (EDAX).  The results show that the tablet is mostly lead with small amount of bismuth, aluminum, calcium, gold, and mercury.  X-ray fluorescence (XRF) also showed the material consisted of lead, iron, and tin.  Slight differences were observed between the two samples, mostly in the amount of the minor chemical components.

The speakers will present work completed in collaboration with their student colleagues Jack Aguilar, JP Bouquet, Hannah Jiam, Millie Shah, and Danny Tang.
