ORGANIC RESIDUE (FTIR) AND SCANNING ELECTRON MICROSCOPE (SEM) ANALYSIS OF SAMPLES FROM THE PRINCE OF WALES FORT NATIONAL HISTORIC SITE, MANITOBA, CANADA

Cork, wood, and glass samples recovered from two barrels and two incomplete bottles
at the Prince of Wales Fort National Historic Site in northern Manitoba, Canada, were submitted
for organic residue analysis. Samples were tested for organic residues using Fourier
Transform Infrared Spectroscopy (FTIR). Organic residue analysis is used to provide
information regarding the contents of the barrels and two glass bottles. A piece of birch bark
bearing a dark red stain from a birch bark container was submitted for identification of this stain.
This piece of bark had been conserved and cleaned, making the stain more visible. A flat rock
that exhibited a beige to brown coating also was recovered at the site and submitted for
analysis of this deposit.
