Early English enslavers sourced copper from Cornwall to create manilla bracelets, the grim currency of the transatlantic slavery trade, and used an impure mix to maximise their profits, according to a study.
Dr Tobias Skowronek, a German scientist, has conducted a scientific analysis of horseshoe-shaped bracelets that were exchanged over hundreds of years for enslaved people from Africa who were transported to Europe, the Americas, and the Caribbean.
