At the National Archaeological Museum of Taranto, in collaboration with the Department of Mathematics and Physics of the University of Salento, a chemical and physical analysis project is currently underway on some of the finds known as Ori di Taranto, with the aim of studying them. the chemical composition and check for any decorations, as well as determine their thickness, to better understand the techniques used to make them.
The study was carried out in situ and with non-destructive techniques, using a portable energy dispersing X-ray fluorescence spectrometer (EDXRF).
Most of the analyzed samples show a similar composition of the alloy (gold, silver and copper, respectively equal to 96.3 +/- 2.0% by weight, 2.8 +/- 1.9% by weight and 0, 9 +/- 0.3% by weight) except nine samples.
The experimental results already obtained offer further research ideas that will be pursued with the continuation of the project.
