Abstract

This study was performed to determine the chemical elements used to produce ancient metallic alloys and to understand the manufacture technique of three archaeological founds. It also presents an evaluation method of the objects’ authenticity based on the observation of the corrosion products. This article also includes three ornamental accessories ca. VII-IV century BC found in the vicinity of Shkodra (Albania). A necklace, a belt application and a button are examined using X ray fluorescence (XRF) to determine the chemical composition and optical microscopy (OM) with reflected and polarised light in order to study the microstructure and the corrosion products. From the XRF results all the objects are bronze, copper-tin and copper-tin-lead alloys. After the OM analysis they are authentic objects (not fake replicas) and might have been produced after a casting process in moulds.
