GR: Red ochre cannot be carbon dated.
SC: It doesn't have to be. There are a number of other means which might allow us to determine if these marks are authentic. Howard-Vyse used gunpowder to blast his way into these chambers. This leaves lead-nitrate spatter on the surfaces. If the inscriptions were painted AFTER the gunpowder explosions then it may be possible to detect lead-nitrate concentrations UNDER the inscriptions. If the inscriptions were extant BEFORE the gunpowder explosions then it may be possible to detect the lead-nitrate concentrations on the surface of the inscriptions.
There may also be pollen or brush fibres trapped in the ochre paint. These can be extracted and examined.
And I am sure there are probably a number of other tests that forensic science could utilise that those outside the field are entirely unfamiliar with.
He said, he said, he said is getting us nowhere. It is now time for real science to try and determine the authenticity of the inscriptions in those chambers.
