Analytical study of a Roman bronze steelyard balance from Leptis Magna, Libya: manufacturing techniques and burial degradation

A Roman bronze steelyard balance from Leptis Magna, Libyareveals advanced manufacturing techniques and severe burial degradation. The artifact, composed of copper and leaded tin bronze (Cu-Sn-Pb), showcases a composite construction with hammered bronze fittings and twisted copper foil chains wrapped around an organic core. Corrosion analysis identified cuprite and chloride-based phases (atacamite and cotunnite), indicating prolonged exposure to chloride-rich soils, which led to the loss of critical functional components like counterweights and scales. This study sheds light on Roman-era trade technologies while providing crucial insights for artifact conservation.
