This technique managed to spot the age of the ink on documents written up to five years previously and with an approximation margin of about 20%.In other words, when applying this analysis procedure, the team can indicate whether the document was written 1,500 days previously (just over four years) with a margin of 300 days either way.Radiocarbon dating: radioactive carbon decays to nitrogen with a half-life of 5730 years.In dead material, the decayed 14C is not replaced and its concentration in the object decreases slowly.

The problems Determining the age of a document to find out whether it is authentic is a task influenced by the type of paper on which it has been written, the pressure of the stroke -the amount of ink deposited when the writing was done- or even the technique used.
