This is Scientific American 60-second Science,I'm Cynthia Graber.This will just take a minute.Iconic works of art get exhibited worldwide.But as those paintings age,they can become to fragile to extend travel around the globe.The paint can be visually examined to gauge 1 its integrity.But the only way to check the canvas has been turning the piece destructively.So a team of researchers in Euro devise a new method for diagnosing the health of the painting similar with testing blood sugar without using a needle.The scientists took samples from nearly 2000 old canvas or canvas linings 2 from the 19 and 20 century.They shine infrared 3 light on the fabric 4 to access the table fiber 5 and the relative fragility.But those results as reference to scientist then scan 20 painting spaces of Salvador Dali .Luckily,our twelves are still in its table travel in condition but they found that the older starlets are starting to weaken.
The research is in the Journal Analytical 6 Methods.The scientists address that the technique because it has only been validated 7 for 19 and 20 century canvas with no synthetic 8 fibres.But to leave what's appreciated of this science of arts ,after all,one of these work is called the armiger to quicken worsen.
Thanks for the minute for Scientific American 60-second Science.I'm Cynthia Graber.
