Profile

Validation of Analytical Methods for a Non-Invasive Characterization of Natural and Artificial Patinas

The research undertaken in the context of the PhD in Archaeological Sciences at UCL will address the study of the patina produced artificially through chemical treatment at the time of creation of the artefact. In particular, the research will treat the main types of intentional patination of archaeological interest, the "Black Bronze" alloys, not often investigated in the archaeometry field, present in Egypt (hsmn-km o hmty-km), Micene (kuwanna), Greece (kyanos) and in the Roman world (Corinhium aes). Alloys that seem to have a more recent origin are the Wu Tong in China and Shakudo in Japan (Irogane class).

Firstly, it will be broadened the knowledge of ancient patinated objects, responding to the several open questions. The second step of the research will be to validate an experimental protocol for the study of patinas, developing a multi-technique system to apply the X-ray fluorescence (XRF) technique to patinated objects, using a non-invasive system, to avoid any alteration of the physical integrity of the artefact, as demonstrated by recent analyses.

Finally, the methodology developed as a result of the previous points would be applied to artificially patinated museum objects, systematically identifying and classifying the "Black Bronzes" in selected Italian and British museums.
