Two weapons showing grey silver like surfaces of the Spanish Late Bronze Age were investigated using SEM and metallography. The coating layer in the best preserved dagger is δ phase tin. This is not in agreement with the experimental results and analytical studies of archaeological items tinned by cassiterite reduction that are described in previous literature. Some conjectures are made to explain this coating layer. [ABSTRACT FROM AUTHOR]

This paper is focused on the analysis of some metallic materials (lead cames and iron supporting elements) from Spanish Medieval stained glass windows of the Monastery of Pedralbes (Barcelona) and the Cathedral of Seville. The main goal of the research was to assess their current state of conservation by studying processes of decay and corrosion due to weathering. The samples were characterised through metallographic examinations, conventional wet chemical analysis, scanning electron microscopy (SEM), energy dispersive X-ray microanalyses (EDX), and X-ray diffraction (XRD). The degree of deterioration has proved to be stronger in iron elements than in lead ones, providing data that are useful for future restoration and conservation of such historical materials and for approaching technological aspects of ancient production processes.
