Radiocarbon dating chemistry
Willard Libby tested during the radiocarbon dating development process was this wood from an ancient Egyptian coffin.The artifact, more than 2,000 years old, dates to the Egyptian Ptolemaic period."Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.The results showed that Ötzi died over 5000 years ago, sometime between 33 BC. It is found in the air in carbon dioxide molecules.£295 ( VAT) per sample for batches of 40 samples or more. 4 weeks) with routine precision: £415 ( VAT) per sample.

The amount of carbon-14 in the air has stayed the same for thousands of years.
There is a small amount of radioactive carbon-14 in all living organisms because it enters the food chain.
The approximate time since the organism died can be worked out by measuring the amount of carbon-14 left in its remains compared to the amount in living organisms.
Benzene radiocarbon dating is discussed in view of recent improved chemistry.
