Researchers from ETH Zurich have refined a process that can detect modern fakes of paintings by measuring excessive levels of the isotope carbon-14 released into the atmosphere through nuclear testing in the 20th century.The new method requires significantly smaller samples of paint than was previously necessary, with a case study demonstrating accuracy dating from a single paint particle weighing under 200 micrograms.Two microsamples from the painting were analyzed, one tiny fiber from the canvas, and a single paint particle weighing around 160 micrograms.Carbon dating of the canvas fiber was consistent with the alleged age of the painting, suggesting the forger cleverly utilized an old canvas to create the fake.Arson investigators look for these items when they're investigating the crime scene.Because all that's usually left of the evidence is charred remains, the investigators will collect fire debris and take it back to the forensics lab for analysis.Samples are sealed in airtight containers and then tested for residues of accelerant liquid that might have been used to start the fire.and enables contractors to provide 'best value' service to maximise coating performance over structure life and to reduce whole life costs.
