ORGANIC RESIDUE (FTIR) AND VISUAL/MICROSCOPIC ANALYSES OF HISTORIC PERIOD SAMPLES FROM SOUTHERN ARIZONA

A ceramic sherd and sediment sample associated with the historic period from southern Arizona were submitted for organic residue and visual/microscopic analyses, respectively. The ceramic sherd was tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Organic residue analysis will be used to determine the materials that have been contained in the vessel represented by the ceramic sherd. Visual and microscopic analysis will be used to identify white linear objects found throughout the sediment sample.
