Conservation

excavation continues in the lab

Archaeological conservation provides for the proper care of at risk artifacts; from their delicate exposure in the field, through mechanical cleaning and chemical stabilization, and finally to secure storage or museum display.

Artifacts comprised of metal, organics, glass, or ceramic are all susceptible to accelerated degradation after excavation, and our conservators intervene to preserve the cultural and physical integrity of the object. Working with both archaeologists and curators, conservators first use non-destructive analytic measures to understand the physical nature of the find and the corrosion products present. All work is thoroughly documented and photographed for future reference.

Corrosion that obscures diagnostic features or is detrimental to the object requires both physical and chemical intervention. Conservators use many different tools; from tiny picks, brushes, and scalpels on small artifacts under magnification, to vibrating air scribes and air abrasion machines to remove bloomed corrosion on larger objects. Additionally, chemical baths and coatings halt chemical reactions on the artifact and deter further degradation.

Mending, creating customized and archival artifact storage, making museum mounts, and ensuring proper temperature and humidity parameters in spaces where artifacts are housed are also part of the responsibilities of the conservation department. Data loggers constantly measure museum conditions, and HVAC control systems alert conservators if conditions fall outside of the established set points. As stewards of artifacts, the collections department, including both curators and conservators maintains the integrity of the Jamestown collection through artifact documentation, dissemination of methods, facilitating access to the artifacts, and creation of security parameters.
