Carbon 14 Dating Mistakes with the Shroud of Turin (Updated in 2008)

Based on . . .

a. Chemistry Today (vol 26 n4/Jul-Aug 2008), "Discrepancies in the radiocarbon dating area of the Turin shroud,"

b. Los Alamos National Laboratory findings (Ohio State Shroud of Turin Conference report (August 2008),

c. Thermochimica Acta (vol 425 2005) and

d. findings of Georgia Institute of Technology chemist John L. Brown,

. . . it can be stated that the 1988 carbon 14 dating of the Shroud of Turin is invalid.

[quote]Although the quality of the radiocarbon testing itself is unquestioned, criticisms have been raised regarding the choice of the sample taken for testing, with suggestions that the sample may represent a medieval repair fragment rather than the image-bearing cloth. It is hypothesised that the sampled area was a medieval repair which was conducted by "invisible reweaving". Since the C14 dating at least four articles have been published in scholarly sources contending that the samples used for the dating test may not have been representative of the whole shroud.

These included a 2005 article by Raymond Rogers, who conducted chemical analysis for the Shroud of Turin Research Project and who was involved in work with the Shroud since the STURP project began in 1978. Raymond Rogers argued in a 2005 article that the chemical analysis he performed on unprovenanced threads sent to him by a clergyman who was not authorized to possess shroud material, show traces of tanning products, likely used by medieval weavers to match the colour of the original weave when performing repairs and backing the shroud for additional protection, and stated: "The radiocarbon sample contains both a gum/dye/mordant coating and cotton fibers. The main part of the shroud does not contain these materials". Rogers stated that after further study he was convinced that: "The worst possible sample for carbon dating was taken." Rogers made his analysis with documented samples. He received 14 yarn segments from the Raes sample from Prof. Luigi Gonella (Department of Physics, TurinPolytechnic University) on 14 October 1979. He took 32 adhesive-tape samples from all areas of the shroud and associated textiles in 1978. On 12 December 2003, He received samples of both warp and weft threads that Prof. Luigi Gonella claimed to have taken from the radiocarbon sample before it was distributed for dating. Gonella reported that he excised the threads from the center of the radiocarbon sample.

Raymond Rogers argued in the scientific journal Thermochimica Acta that the presence of vanillin differed markedly between the unprovenanced threads he was looking at, which contained 37% of the original vanillin, while the body of the shroud contained 0% of the original vanillin. He stated that: "The fact that vanillin cannot be detected in the lignin on shroud fibers, Dead Sea scrolls linen, and other very old linens indicate that the shroud is quite old. A determination of the kinetics of vanillin loss suggest the shroud is between 1300- and 3000-years old. Even allowing for errors in the measurements and assumptions about storage conditions, the cloth is unlikely to be as young as 840 years". Rogers concluded from this that the Shroud is much older than the earlier purported estimates. Rogers also noted that the thread he examined contained a significant amount of cotton, and stated that cotton was absent in the main-body of the Shroud.

Science Shines New Light on Shroud of Turin’s Age

While questions have been raised about his methodology, an Italian researcher’s novel use of test procedures suggests the shroud is indeed 2,000 years old.
