Analysis & Consolidation of Q1 Artifacts

In the laboratory this week, we have been processing the artifacts recovered from our recent project through analysis and consolidation. For the more friable pottery and earthenware, these artifacts will be protected from the environment with an aqueous solution of 10% polyvinyl acetate-polyvinyl alcohol-propylene glycol emulsion. The solution is thin enough in viscosity to permeate surface layers of the artifact and reinforce it’s structure. The artifacts are then cured under a high-energy wavelength light at 395 nanometers for roughly 45 minutes or until the glaze sets on the artifact. This will ensure that the artifact retains its authentic form and structure from the marine environment it was recovered from.

The paleontological remains and glassware recovered from this project were cleaned of calcareous material and washed in de-ionized fresh water to remove soluble salts (chlorides, phosphates, and nitrates). The rinse was monitored with a conductivity meter. All fossils were lightly cleaned with a 3% hydrogen solution to remove calcium deposits, sulfide staining, sulfate-reducing bacteria, and excess organic debris. All artifacts are stored in individual polyethylene enclosed bags in low humidity containers.
