14 c dating fiasco shroud turin
Thus, he concluded that it must date from medieval times.
He believes that vanillin is also present in the "Holland cloth" used to patch the shroud.
But before it could be used to date real materials, it had to be calibrated by using the technique on samples whose ages were independently known.
Rogers has not performed this type of calibration on vanillin analysis.
"This incident just underlines the fact that the Shroud of Turin will never go away, and believers will try anything, including arguments masquerading as science, to prove its authenticity." Jay Ingram, host of Daily Planet of the Canadian Discovery Channel.
Rogers developed a new method of dating linen based on its vanillin (a.k.a. Rogers believes that vanillin is detectable in the sample taken for radiocarbon testing.Unfortunately, bleaching methods have changed over the centuries, and so no accurate age measurements could be made.Carbon-14 radiometric measurements have had an excellent track record and are the analytical technique of choice. As linen ages, the vanillin content declines and eventually becomes undetectable.Describing the C-14 sample collection, scientist P. Damon indicated that textile experts took care to select a site from which to take the sample that was some distance from patches and seams.Rogers believes that the Carbon-14 results measured by three laboratories in 1988 are thus closer to the date when the shroud was repaired than to the date when it was originally woven from fibres of the flax plant.
