If the requirements are favourable, the exact concentration of the alloy can be determined.<\/p>\n<ul>\n<li><b>The authentication of an art works and looking for forgeries<\/b><\/li>\n<\/ul>\n<p>The characterization of the corrosion products can help to differentiate natural alteration from artificial ones produced in a purpose of forgery. The concentration of an alloy may also be correlated with specific modes of manufacturing of an artist, a country or for a period in history.<\/p>\n<ul>\n<li><b>An asset for restoration<\/b><\/li>\n<\/ul>\n<p>The information provided by the analyses help the conservators and restorers for choosing the most suitable mode of restoration according to the dangerousness of the
