Abstract
Pre-Columbian smiths working in northern Peru gilded and silvered copper objects by electrochemical replacement techniques that deposited films of 0.5-2 mum onto copper sheet. Platings that seem to be identical have been produced in the laboratory using gold dissolved in aqueous solutions of NaCl + KNO<sub>3</sub> + KAl(SO<sub>4</sub>)<sub>2</sub>. 12H<sub>2</sub>O. -- AATA
