On January 13, 2016 Dr. Jayne Wilkins from the University of Cape Town, South Africa, held a workshop in the Lithic Microwear Lab. This workshop taught interested students the practical applications of using ArcGIS software in the quantification of lithic use-wear traces. As part of this experimental workshop, attendees were tasked with repeatedly cutting into a pork picnic roast using the flake of their choice. Care was taken that the blade only contacted the meat and bone (not the table) so that the wear accrued could be accurately attributed to butchering. The cutting action was tabulated by strokes with each flake being used 25 to 100 times in order to create edge damage that could then be mapped in using ArcGIS. Once mapped in, the attendees were shown how to translate those segments of potential edge damage (PED) into quantifiable data that could be graphed, statistically analyzed and visually presented.
