The second of my series of Research Dumps. This issue includes Medieval Metal accessories, BEADS!, a report on a fascinating find, Irish book satchels, Mongolian clothing, and others.
TIN AND TINNED DRESS ACCESSORIES FROM MEDIEVAL WROCŁAW (SW POLAND). X-RAY FLUORESCENCE INVESTIGATIONS
Abstract:
This paper presents a non-destructive analytical study of selected archaeological artefacts from the Old Town in Wrocław, SW P...oland, by energy-dispersive X-ray fluorescence spectrometry. The analysed specimens included dress accessories that decorated both womens
and mens clothes in the Middle Ages. Several various metallic artefacts were selected for detailed studies: jewellery (e.g. finger rings) to more utilitarian utensil (functional) items (e.g. knives). All of them were made of tin-lead alloys or were tinned. This research was
focused on determining the chemical composition of the artefacts, the identification of similarities and differences between alloys as well as technological aspects of the production.
The obtained results suggest that there are many objects with the same chemical composition. It helps to distinguish groups of artefacts (e.g. rings made with the same alloys) or find the
parts of one object. The next interesting result is the possibility of determining the presence of tin-plating that was in varied states of preservation (especially for badly damaged artefacts).
Included are some photographs of the pieces being studied.
