Dating Archaeological Copper/Bronze Artifacts by Using the Voltammetry of Microparticles

A method for dating copper/bronze archaeological objects aged in atmospheric environments is proposed based on the specific signals for cuprite and tenorite corrosion products measured through the voltammtry of microparticles method. The tenorite/cuprite ratio increased with the corrosion time and f...

Summary:A method for dating copper/bronze archaeological objects aged in atmospheric environments is proposed based on the specific signals for cuprite and tenorite corrosion products measured through the voltammtry of microparticles method. The tenorite/cuprite ratio increased with the corrosion time and fitted to a potential law that yielded a calibration curve usable for dating purposes. The dating game: A method for dating copper/bronze archaeological objects (see example) aged in atmospheric environments is proposed based on the measurement of specific voltammetric signals for cuprite and tenorite corrosion products. The tenorite/cuprite ratio increased with the corrosion time, fitting to a potential law that yielded a calibration curve usable for dating purposes.
