Aims

The module introduces the archaeology and scientific analysis of ancient and historic metals, with special reference to copper alloys. By taking the the module, you will learn (1) how people mined and smelted the ore in antiquity; (2) how to understand the chemical composition of ancient metals by XRF analysis; (3) how to understand the microstructure and mechanical properties of metals by metallography; (4) how corrosion may alter the surface of ancient metals; and (5) how to understand manufacture and use of copper alloy tools and weapons by Metalwork Wear Analysis. As part of the module, you will learn and practise two cutting-edge techniques of metal analysis: metallography (including sample preparation and polishing); and metalwork wear analysis (using a stereomicroscope). You will also take part in a metal casting and working experiment to develop first-hand experience and practical understanding of some of the concepts introduced during classes. Teaching resources include archaeological metal artefacts from the Great North Museum collections, ore/mineral specimens, and replica Bronze Age objects from the School’s own teaching collections. The course is open to all Master’s students as it does not require any background knowledge of chemistry or materials science.

Aims
• To provide students with a critical understanding of ancient metals (especially copper alloys) including their extractive and manufacturing technologies.
• To provide students with the theoretical and practical skills needed to carry out metallography and metalwork wear analysis safely and independently.
• To introduce metalwork microstructure and surface corrosion.
• To introduce alloy composition analysis by X-Ray Fluorescence.

Assessment Rationale And Relationship

- The class exam (multiple-choice quiz) evaluates knowledge and understanding of phase diagrams and alloy properties.
- The 3000 word analytical report evaluates students’ ability to carry out the Metalwork Wear Analysis of a small assemblage of archaeological copper alloys safely, proficiently, and independently. It also tests their ability to critically interpret the analytical data in light of the archaeological literature and draw inferences of general validity. The report shall include an archaeological contextualisation of the objects.
- The formative assessment - a 500 word reflective log commenting on the lab casting and metalworking experiment - helps students reflect on how experimental/practical knowledge enhances and complements academic/scientific learning
