Field Session:
Through a tour of the Clemson University Restoration Institute in North Charleston, you will explore how conservators, archaeologists and scientists at the Warren Lasch Conservation Center (WLCC) mitigate metal corrosion challenges encountered when dealing with artifacts recovered from marine environments. This field session will cover traditional and innovative metal conservation protocols and research established since the recovery of the H.L. Hunley submarine and its artifacts. The use of subcritical fluids technology in experimentation at the WLCC, which offers a unique solution to the stabilization of corrosion products, will be discussed. These metal conservation methodologies have been applied to the Hunley Project, but also to a range of other metallic artifacts from a variety of provenances. Various metals artifacts will be mentioned with an emphasis on the conservation of cast and wrought iron. Additionally, analytical and documentation techniques employed will be discussed and demonstrated.
