Forensic scientists are sometimes called to help analyze evidence left from a hit-and-run or possible case of arson.
They have special techniques to study what's often small or extremely damaged evidence.
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.
This increased volume of carbon-14 can be found in every organic material that has been generated since the 1960s.
For some time the idea of tracking art forgeries by measuring levels of carbon-14 in their materials has been suggested, however it was fundamentally unfeasible until recently due to the volume of samples required for the measurement.
If old samples of paint have been mixed with a modern binder this means any tested artwork would inevitably be significantly damaged in order to obtain enough of a sample to trace its authenticity.Finally, Libby had a method to put his concept into practice.After finding more water jar pieces, researchers plan their return to Cara Blanca, Belize, to further study the Maya world and how its inhabitants survived multi-year droughts.This new method of detecting forgeries is not without its limitations of course.It is estimated that atmospheric carbon-14 levels are rapidly returning to baseline pre-1950s levels.
