Ascertaining the function of tools and other archaeological objects has, in the last three decennia, advanced with great leaps and bounds. Microscopic analysis of wear traces is central to this. With the use of various types of microscope it is now possible to establish the function, use and means of production of many tools and objects within a large number of material categories. Not only stone or flint but also bone, antlers, shell and coral. In combination with analysis of whatever residues might be present this can deliver very specific information over these materials and how they were treated.
The University of Leiden has the necessary expertise to carry this out.
