Abstract
In an attempt to provide objective measures of the changes induced in chert by heat treatment, ten pairs of preforms were made, and one of each pair was heat treated, using a probable aboriginal technique. Paired bifaces were then chipped from the preforms. Differences in the flaking qualities of the heated and the unheated materials were noted. The bifaces made with the heat treated material were significantly thinner in cross-section than those made from raw material. Analysis of the debitage indicates that heat treatment fosters the removal of larger flakes.Keywords
