“…This has promoted growing interest in the scientic analysis of paintings to help authenticate authorship, to detect forgery and to date and determine the provenance of the materials used in artworks. [1][2][3] The goal of scientists is to establish whether the materials in the artwork are consistent with those used in the times of the attributed artist. The conrmation or rejection of authorship of paintings in some cases of controversial or doubtful attribution is a difficult and challenging task, which in the case of many precious works of art remains incomplete.…”

A B S T R A C TThe study of valuable Cultural Heritage objects frequently requires non-destructive analysis with good sensitivity. Moreover, it is often necessary that the measures are carried out in-situ, in particular when transport of the items from the institutions to the laboratory is not allowed.In this work, the technical specifications of the micro-XRF spectrometer developed at the CNA in Seville is presented and its analytical capabilities are tested by means of the analysis of a set of Etruscan gold jewels of the National Archaeological Museum of Florence. Since these jewels are characterized by elaborate decorations, with details of typical dimensions down to tens of microns, a high lateral resolution is required to study the features of these objects. The challenge consists in the characterization of the welding/soldering zones and the details of the jewels that present a very complex geometry. This paper shows the micro-XRF in-situ analysis of 15 Etruscan gold jewels (from the VII century BCE) in order to characterize the alloy composition of sheets, threads, filigrees, granules, as well as the joining zones. Based on these results, the manufacture technique and the production process employed by the Etruscan goldsmiths could be described.
