Under the hammer: Residues resulting from production and microwear on experimental stone tools

Abstract

This paper presents the results of an experimental programme investigating the effects of production processes on stone tools and their interference with use-related features. In the first part of the experimental programme, a series of flint flakes was retouched with different kinds of hammers in order to assess the extent and nature of percussion residues. After careful environmental scanning electron microscope (ESEM) observation and energy-dispersive X-ray (EDX) analysis, the retouched flakes were thoroughly cleaned and the underlying flint deformation was recorded. The second part of the experimental programme involved selecting several uncleaned retouched pieces for use in short woodworking, hide-processing and butchery experiments. These pieces were observed and analysed before, during and after use. Some of the percussion features proved to be surprisingly resistant to use, and in some cases turned out to be strikingly similar in appearance to use-generated features. © University of Oxford, 2006.
