April 18 - 21, 2017 and April 24 - 27, 2017
Colonial Williamsburg, Williamsburg, VA
Instructor: Valentin Boissonnas
Organizer: Emily Williams
Archaeological iron is one of the most problematic materials to come out of the ground as it can develop post-excavation corrosion that can destroy artifacts in a relatively short period of time.
This four-day workshop will focus on the following topics:
- pre-industrial iron smelting technology
- iron transformation
- formation of iron corrosion products in the soil
- preservation of the limit of the original surface within corrosion layer
- post-excavation corrosion phenomena
- storage and stabilization treatments of archaeological iron
Hands-on experience will be given with mechanical cleaning and x-raying of archaeological iron artifacts from excavations from Colonial Williamsburg.
