Metallography is the study of the physical structure and components of metals. This tool can be used by archaeologists, conservators and scientists to understand exactly how ancient people created objects. The microstructure of the metal is revealed after etching and can be used to determine whether copper alloys are simply cast or have been worked. In iron and steel metallography can be used to determine the carbon content and also what heat-treatments have been applied, welding techniques and manufacturing methods.
I can provide a one day theoretical course on metallography of ancient artefacts for archaeologists, archaeological scientists or conservators. The course can be tailored to the specific audience and will cover
- Phase diagrams
- Copper alloy microstructures, use of lead, hot and cold working
- Iron and steel microstructures and determining carbon content
- Heat-treatments and working of iron alloys
- Case studies will be used
