Using ion beams to detect art forgery

University of Notre Dame nuclear physicists Philippe Collon and Michael Wiescher are using accelerated ion beams to pinpoint the age and origin of material used in pottery, painting, metalwork and other art. The results of their tests can serve as powerful forensic tools to reveal counterfeit art work, without the destruction of any sample as required in some chemical analysis.

Their research is featured on the front cover of the current issue of Physics Today in an article titled, “Accelerated ion beams for art forensics.” Wiescher and Collon say, “Art experts play an important role in identifying the style, history and context of a painting, but a solid scientific basis for the proper identification and classification of a piece of art must rely on information from other sources.

“A host of approaches with origins in biology, chemistry and physics have allowed scientists and art historians not only to look below a painting’s or artifact’s surface, but also to analyze in detail the pigments used, investigate painting techniques and modifications done by the artist or art restorers, find trace materials that reveal ages and provenances, and more,” Wiescher and Collon continue.

The information that is revealed can shed light on trading patterns, economic conditions and other details of history. For example, the amount of silver in Roman coins can indicate the degree of inflation in the ancient economy.

    Now, this sounds just the gadget to check out some mystery French pottery. I can’t remember the name of it now. It “emerged” in France, some time at the end of the 19 or possibly early 20 C. None of the experts could tell whether it was fake or genuine ancient pottery. There was no excavation site so it was impossible to relate it to context. This is a poser for you, Jim, because I have not been able to provide many clues, but it was a big mystery which divided expert opinion. This is always fun, and I never got to hear whether new techniques had resolved the issue.

    Sorry Alfy, I’ve failed to find any mention of suspect pottery found in France. Probably need a few more clues.
