CASHP Student Expands Interdisciplinary Research

Collaborations between Engineering and Archaeologists Highlighted in PLOS One
November 18, 2014

A new study by CASHP student (A. Zipkin) and faculty (A. Brooks) with collaborators in the Department of Mechanical and Aerospace Engineering bridges archaeology and materials science to investigate how Stone Age composite tools were constructed with hafting adhesives.  People in Middle Stone Age Africa seemed to favor adding red ochre to their hafting glue as a binder but three years of experiments measuring adhesive toughness indicated that there are a variety of ways to construct a strong and durable composite tool.  Is the use of red pigment as a binder evidence of symbolic behavior?
