DOCUMENT Full-Text Melissa K. Logan. Linda Scott Cummings.

A ceramic effigy vessel recovered from the Wallace Site (5MT6970) in Montezuma County, southwestern Colorado, was submitted for organic residue analysis. Organic residues were tested using Fourier Transform Infrared Spectroscopy (FTIR). Multiple test extractions were performed on the vessel in an effort to isolate and remove contaminants imparted on the vessel by labeling ink before a final extraction was performed to remove the organic residues from the interior of the vessel.
