ISAS Makes Use of 3D Profiler at Material Research Laboratory

Madeleine Evans, Eve Hargrave, Dr. Kristin Hedman, and Dr. Laura Kozuch attended a demonstration of the Material Research Laboratory’s 3D profiler. ISAS staff brought in examples of incised modified bone, tooth, and shell. The 3D profiler was able to measure and document the shapes of fine incisions on these materials. The profiler was also able to map differences in surface roughness on a sandstone mortar and identify differences in microwear on a chert endscraper. This technology does not require any kind of pre-treatment to materials and has great potential when working with very fragile artifacts. This is a great example of how ISAS uses new technology to facilitate research and answer archaeological questions.
