Abstract

The goal of this thesis was to determine if subsistence residue could be extracted from ceramics affiliated with the Karankawa. This was done by attempting to identify the potential residue compound signatures expected to be absorbed within ceramic vessels that may have been used for food preparation. This thesis discusses the results of residue analyses conducted on ceramics obtained from two Karankawan sites, the prehistoric Guadalupe Bay site (41CL2) and the Spanish Colonial Mission Nuestra Señora del Refugio (41RF1) sites in Texas. The extraction of the absorbed residues and the biochemical analysis of the compounds were performed at Millsaps College Keck Lab through the use of gas chromatography mass spectrometry (GC-MS) machinery. Once all samples were archaeometrically processed the results would have been interpreted for subsistence however valid results were not obtained.
