Abstract
Investigations of gilded cooper metalwork from the Moche cemetery at Loma Negra have shown that the gilding method used differs significantly from that observed on Moche metalwork from centres further to the south. A comparative analysis of gold layers on copper sheet artifacts from Loma Valley (north coast Peru), was carried out at The Metropolitan Museum of rt using metallography, energy dispersive X-ray spectroscopy (EDS) and scanning electron microscopy (SEM). The results suggests that the local Vicús population and the Moche at Loma Negra shared some aspects of their metallurgical traditions.
