Abstract

Several pieces and fragments from the Museum of Huaca Rajada site, Sipan, were analyzed by various techniques to determine the type of alloy and elemental composition. Techniques used have been the x-rays fluorescence (EDXRF) and scanning electron microscopy (SEM). EDXRF measurements were made by using a laptop brand Amptek and SEM measurements were made in the laboratories of the Consiglio Nazionale della Ricerca (CNR, Montelibretti headquarters, Rome). The objects found in the Museum of Sipan were selected according to their importance and composition. Tumbaga kind pieces, gilded copper, gilded silver, bronze and arsenical copper was found. Measurements by SEM showed the layers of gold and silver in the case of gold and silver plated copper. The results showed the type of alloy in each case and could be determined in some cases the thickness of the gold or silver.
