Laser scanning confocal microscopy has proved to be a promising technique in the identification of how prehistoric stone tools were used. Published research has shown that basic roughness parameters can characterise wear produced experimentally by different activities on the edges of stone tools (working different materials such as hide, wood and antler). However, it is important to understand other variables before these methods can be applied to archaeological artefacts. For example, it is not yet known how duration of use influences the texture characteristics of worn surfaces. This report presents a study of two contact materials (antler and wood) with variation in the duration of stone tool use. This research produces interesting results that indicate texture characteristics stabilise for antler but the results for wood working are more complex. The results instigate a discussion of sampling processes and future analytical strategies. This report presents the details of this research and other experiments that contribute to the development of applied methods in quantitative lithic microwear analysis.
