Nuclear dating methods
Forgers have reused old canvases to create forgeries, neutralizing the effectiveness of testing canvas fibers.And historically, large samples were needed to conduct the analyses.Mid-20th-century nuclear bomb tests may hold a clue.For years, scientists have been refining techniques to determine the age of a painting using radiocarbon dating and the lingering effects of the tests.It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.How can you tell if a painting is a modern forgery?
As a result, scientists can determine the age of dead organic matter up to tens of thousands of years old by calculating the ratio of those carbon isotopes.
Atoms of a single element but of different masses are known as isotopes.
The carbon 12 and carbon 13 isotopes are stable, while carbon 14 is unstable.
The samples were taken from a known forgery, a painting of a 19th-century village scene that was claimed to have been created in 1866.
In reality, the work had been painted in the 1980s by Robert Trotter, an artist who was later jailed and fined for selling dozens of such fakes.
