on the nature of the alloy and the greater affinity of copper for sulphur. The dissolution of Ag and Cu to form corrosion products was proposed as the rate determining step. Key words: silver; conservation and restoration; tarnishing; electrochemical impedance spectroscopy; silver alloys; corrosion mechanism 1 Introduction Silver is usually found in its native form or as an alloy with other metals (e.g., Cu......
