The Shroud of Turin, a linen cloth that tradition associates with the crucifixion and burial of .. He also added that there is as yet no direct evidence to suggest the original radiocarbon dates are not accurate. In , Ramsey commented that in . We are only two years away from a fresh exhibition of the Turin Shroud [occurring in ]-- and with . explaining what went wrong with the radiocarbon date. Rogers' findings were that the samples were invalid and indeed the Shroud is significantly older than the carbon 14 dating suggested.

Rogers took 32 documented adhesive-tape samples from all areas of the shroud and associated textiles during the STURP process in On 12 DecemberRogers received samples of both warp and weft threads that Luigi Gonella claimed to have taken from the radiocarbon sample before it was distributed for dating.

The actual provenance of these threads is uncertain, as Gonella was not authorized to take or retain genuine shroud material, [45] but Gonella told Rogers that he excised the threads from the center of the radiocarbon sample. He stated that his analysis showed: The main part of the shroud does not contain these materials. Based on this comparison Rogers concluded that the undocumented threads received from Gonella did not match the main body of the shroud, and that in his opinion: It may not have taken us long to identify the strange material, but it was unique amongst the many and varied jobs we undertake.

She has rejected the theory of the "invisible reweaving", pointing out that it would be technically impossible to perform such a repair without leaving traces, and that she found no such traces in her study of the shroud. Gove helped to invent radiocarbon dating and was closely involved in setting up the shroud dating project. He also attended the actual dating process at the University of Arizona. Gove has written in the respected scientific journal Radiocarbon that: If so, the restoration would have had to be done with such incredible virtuosity as to render it microscopically indistinguishable from the real thing.

Even modern so-called invisible weaving can readily be detected under a microscope, so this possibility seems unlikely. It seems very convincing that what was measured in the laboratories was genuine cloth from the shroud after it had been subjected to rigorous cleaning procedures. Probably no sample for carbon dating has ever been subjected to such scrupulously careful examination and treatment, nor perhaps ever will again.

Atkinson wrote in a scientific paper that the statistical analysis of the raw dates obtained from the three laboratories for the radiocarbon test suggests the presence of contamination in some of the samples.

They examined a portion of the radiocarbon sample that was left over from the section used by the University of Arizona in for the carbon dating exercise, and were assisted by the director of the Gloria F Ross Center for Tapestry Studies.

They found "only low levels of contamination by a few cotton fibers" and no evidence that the samples actually used for measurements in the C14 dating processes were dyed, treated, or otherwise manipulated. They concluded that the radiocarbon dating had been performed on a sample of the original shroud material.

A determination of the kinetics of vanillin loss suggest the shroud is between and years old. Even allowing for errors in the measurements and assumptions about storage conditions, the cloth is unlikely to be as young as years". Others contend that repeated handling of this kind greatly increased the likelihood of contamination by bacteria and bacterial residue compared to the newly discovered archaeological specimens for which carbon dating was developed.

Bacteria and associated residue bacteria by-products and dead bacteria carry additional carbon that would skew the radiocarbon date toward the present.

the biggest carbon 14 dating mistake

Rodger Sparks, a radiocarbon expert from New Zealand, had countered that an error of thirteen centuries stemming from bacterial contamination in the Middle Ages would have required a layer approximately doubling the sample weight. Pyrolysis-mass-spectrometry examination failed to detect any form of bioplastic polymer on fibers from either non-image or image areas of the shroud.

Harry Gove once hypothesised that a "bioplastic" bacterial contamination, which was unknown during the testing, could have rendered the tests inaccurate. He has however also acknowledged that the samples had been carefully cleaned with strong chemicals before testing. Others suggested that the sample was contaminated with residue from a damaging fire in But the scientists who conducted the carbon 14 tests refuted these suggestions.

The Biggest Radiocarbon Dating Mistake Ever

They denied that the sample was taken from a damaged area and they argued that any residue from the fire would have been removed during the sophisticated cleaning process that precedes actual testing.

Leoncio Garza-Valdes, a Texas pediatrician and amateur archeologist, and Stephen Mattingly of the University of Texas offered another suggestion. They claimed that they found an organic bioplastic contamination on the Shroud that would not have been removed with the cleaning process that the labs had used. The bioplastic idea gained traction among many Shroud researchers when Harry E. Gove, a nuclear physicist at the University of Rochester who designed the carbon-dating methods used on the Shroud, gave tentative support to Garza-Valdes and Mattingly.

Sheler, writing in the July 24,issue of U. But the bioplastic idea came up short. For one thing, there is no way to determine the definitive composition of an organic material by scanning electron microscope. Furthermore, it is well known that such polymers obtain their carbon material from the host fibers in this case and not from the atmosphere, hence they would not significantly alter the carbon 14 dating. On this point, Gove took exception with the bioplastic theory by explaining that the quantity of biological material would be very significant.

Because significant material could be easily detected, fibers from the Shroud were examined at the National Science Foundation Mass Spectrometry Center of Excellence at the University of Nebraska.

Pyrolysis-mass-spectrometry examination failed to detect any form of bioplastic polymer on fibers from either non-image or image areas of the Shroud. As it turns out, those who suggested that the carbon 14 samples were from a rewoven area were right. This is what was reported in Thermochimica Acta on January 20, Thermochimica Acta is not the sort of journal you will find in the reading room of public libraries.

It is mainly for chemists. It is a peer reviewed journal which means that articles are carefully examined by other scientists to ensure that the science is true, methods are sound, and all explanations and conclusions are completely free of logical fallacies.

Peer review, an exacting process of challenge and correction, is the normal way that scientists announce their findings. Carbon 14 Dating Scientists Fooled When the Piltdown man hoax was uncovered insophisticated chemical analysis techniques, developed in part by Teddy Hall, showed that skull fragments and other bone pieces had been expertly dyed to look older and match each other.

This was done to fool people into thinking the bones were very old. People were fooled and many thought that the Piltdown man might be the missing link. In the case of the Shroud of Turin, it was threads were dyed to look older and to match other threads. It was a small area in one corner of the Shroud where some mending threads had been dyed to look like the rest of the age-yellowed Shroud.

Chemical analysis proves this. There is absolutely no doubt about that. In the case of the Shroud it was the carbon 14 testers that were fooled. And they should not have been fooled. There were clues that warranted investigation: InGilbert Raes of the Ghent Institute of Textile Technology was given permission to remove a small sample from a corner of the Shroud.

In the sample he found cotton fibers.

It might have been that the cotton was leftover fibers from a loom that was used for weaving both cotton and linen cloth. It might have been that the Shroud was exposed to cotton much later, even from the gloves used by scientists.

However, when later he examined some of the carbon 14 samples, he noticed that cotton fibers, where found, were contained inside threads, twisted in as part of the thread. It is important to note that cotton fiber is not found anywhere else on the Shroud. H South, while examining threads from the sample on behalf of the Oxford University Radiocarbon Dating Laboratory found similar indication of cotton.

To him it seemed like material intrusion. In an article entitled "Rogue Fibers Found in Shroud," published in Textile Horizons inSouth write of his discovery of "a fine dark yellow strand [of cotton] possibly of Egyptian origin, and quite old.

Giovanni Riggi, the person who actually cut the carbon 14 sample from the Shroud stated: The question should have been asked: It is not found elsewhere on the Shroud. In the years following the carbon 14 dating, in the years when careful reexamination seemed warranted, other compelling reasons to be suspicious emerged: If the Shroud was medieval, it should have. Vanillin disappears slowly from the lignin in flax fibers and all of it has disappeared except in the immediate vicinity of the carbon 14 sample.

This indicated that the cloth was much older than the carbon 14 dating suggested and that the carbon 14 sample area was certainly chemically different. One part of it contained cotton fibers among the flax fibers while another part of it did not. Moreover, Rogers found dyestuff and spliced threads that were not found elsewhere on the Shroud. It is significant to note that the carbon 14 sample was taken from a spot adjacent to the Raes sample.

Marino, working with a number of textile experts, examined documenting photographs of the carbon 14 sample and found evidence of expert reweaving that joined disparate materials almost at the middle of the sample. If that is the case, and if the repair was made in the early s as history suggests, then according to Ron Hatfield of Beta Analytic, a first century date for the cloth is reasonable.

Significantly, he found serious disparities in measurements between the three laboratories and between the sub-samples various tests and observations performed by the labs. The essential conclusions were that the samples, and indeed the divided samples used in multiple tests, contained different levels of the carbon 14 isotope.

The differences were sufficient to concluce that the sample were non-homogeneous and thus of questionable validity. Walsh found a significant relationship between various sub-samples and their distance from the edge of the cloth.

If indeed a patch was rewoven into the cloth and if the joining of old and new material ran at an angle through the sample cuttings as it appears to do so then all this makes sense. Carbon 14 Dating Samples Studied In DecemberRogers was able to obtain material from the actual carbon 14 sample cutting used for testing in This material had been saved from the center of the carbon 14 samples before they were distributed to the carbon 14 laboratories.

What Rogers found proved that the sample was bad. He found threads encrusted with a plant gum containing alizarin dye; a dye that is extracted from Madder root.
