A Technical Study on Manufacturing Technique and Corrosion Inspection of Bronze Age Metal Artifacts Excavated from Shahr-e Sukhteh Cemetery

A technical analysis of Bronze Age metal artifacts from Shahr-i Sokhta reveals that arsenic, zinc, and lead were present in the studied samples, suggesting a shared origin. However, high corrosion levels hinder definitive conclusions about their provenance. Microstructural examinations indicated fine grain size, hammering, and annealing processes. Corrosion products such as Cuprite, Malachite, Paratacamite, and Atacamite were identified using X-ray diffraction (XRD). The study employed Scanning Electron Microscopy/Energy Dispersive Spectroscopy (SEM-EDS), metallography, and radiography to investigate manufacturing techniques and corrosion processes. These findings contribute to understanding the technological and material practices of ancient Bronze Age civilizations in the region.
