FTIR spectroscopy has played an important role in identification of fire residues in prehistory. In particular, burnt bone is often classified using this technique. I am exploring the effects that variables such as temperature and burning duration may have on the appearance of the FTIR spectrum of burnt bone. Through exploration of the bone chemistry, I aim to understand the thermal alteration of the bone mineral, and therefore induce whether other diagenetic processes would produce similar spectra to that of burnt bone. I applied these results to the site of Wonderwerk Cave, South Africa, to determine if the fauna excavated from the context of 1.78Ma were burnt.
