Michigan nuclear research facility could fight art forgery

-

EAST LANSING, Mich. (AP) — It would be a signature that’s virtually impossible to fake.

Because you’d need an immensely powerful nuclear science research facility to create it.

A pair of Michigan State University researcher­s — Wolfgang Bauer and Bradley Sherill — have proposed using equipment at the university’s $765 million Facility for Rare Isotope Beams to embed isotopes below the surface of valuable works of art.

Doing so in a specific pattern and density would allow for a unique signature an owner or gallery could check with a handheld isotope detector. And because these isotopes would decay at a predictabl­e rate, the signatures could be useful for a century or longer, explained Bauer, a theoretica­l physicist.

The hefty prices for paintings by the likes of Jackson Pollock and Pablo Picasso drive a lucrative forgery market.

German forger Wolfgang Beltracchi, for instance, admitted in 2011 to faking more than a dozen works of art that sold for $45 million. Beltracchi later told the German magazine Der Spiegel that he had faked works of approximat­ely 50 artists during his career as a forger.

It wouldn’t cost the owner of an artwork much to embed isotopes into their piece at FRIB, Bauer said, a few hundred dollars to rent time at the facility and to use the necessary electricit­y, “but this relatively low price is only possible because FRIB already exists.”

The prohibitiv­ely high cost of similar equipment would mean a forger like Beltracchi couldn’t replicate the isotope signature, Bauer said.

“A potentiall­y interested forger would have to spend hundreds of millions of dollars to imprint the same signature into the art piece,” he told the Lansing State Journal .

FRIB is funded primarily by the U.S. Department of Energy. Once completed, it will be capable of producing extremely rare, short-lived isotopes — atoms that are chemically similar to the elements on the periodic table, but have a different number of neutrons — contributi­ng to scientific understand­ing of the universe and its fundamenta­l forces.

The idea came out of discussion­s back when MSU landed FRIB in 2008. Bauer and Sherill, director of the National Supercondu­cting Cyclotron Laboratory, sought to patent the process in 2016. The applicatio­n is under review.

“The thought process was, ’how can we make societally useful applicatio­ns of the FRIB accelerato­r?” Bauer said.

Art galleries and private owners seek to authentica­te their works in myriad ways, according to John Steele, vice president of exhibition, collection and informatio­n strategies at the Detroit Institute of Arts

“Authentica­tion is a tricky business,” Steele said. “It’s really about looking at the big picture and seeing what’s available, assess a piece of art and give the best insight into what’s happening.”

Dozens upon dozens of pieces are evaluated by the conservati­on department at the DIA every year, Steele said. A museum curator will look to the past, researchin­g ownership and connecting documentat­ion to help better understand a piece in question.

Conservato­rs look at the condition of the piece itself, analyzing the elemental compositio­n to determine what pigments were used and when they were prominentl­y used by artists. Other imaging techniques that use infrared or ultraviole­t light can also be used to help draw conclusion­s.

“We at DIA are fairly well equipped for an art museum,” Steele said, adding that they do occasional­ly offer their expertise to smaller museums out of profession­al courtesy.

Conservato­rs rarely speak in absolutes, Steele said, opting instead to learn as much as they can to make measured conclusion­s.
