Although atomic number 82 carbonates contain radiocarbon, until at nowadays at that spot was no method to carbon appointment the chemic chemical compound directly.

Lucile Beck together with authors at nowadays supply a agency to stair out the historic menstruation of atomic number 82 carbonates. The authors role the method to decide the historic menstruation of make-up samples constitute inward ancient Egyptian together with Greek tombs dating from 1500-200 BC. Since this method relies on carbon incorporated into the atomic number 82 carbonate at the fourth dimension it was made, natural pigments tin live on distinguished from man-made samples.

The authors propose that this method offers archaeologists a valuable agency to appointment ancient materials. It may besides live on used to appointment fine art together with paintings, since atomic number 82 carbonate was used every bit a mutual white pigment throughout history.
