The Shroud of Turin (Turin Shroud), a linen cloth that tradition associates with the crucifixion and burial of Jesus, has undergone numerous scientific tests, the most notable of which is radiocarbon dating, in an attempt to determine the relic's authenticity. Shredding the samples would not solve the problem, while making it much more difficult and wasteful to clean the samples properly.
It may not have taken us long to identify the strange material, but it was unique amongst the many and varied jobs we undertake.” The official report of the dating process, written by the people who performed the sampling, states that the sample "came from a single site on the main body of the shroud away from any patches or charred areas." Mechthild Flury-Lemberg is an expert in the restoration of textiles, who headed the restoration and conservation of the Turin Shroud in 2002.
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.
The blind-test method was abandoned, because the distinctive three-to-one herringbone twill weave of the shroud could not be matched in the controls, and it was therefore still possible for a laboratory to identify the shroud sample.
group expected to perform the radiometric examination under its own aegis and after the other examinations had been completed, while the laboratories considered radio-carbon dating to be the priority test, which should be completed at the detriment of other tests, if necessary.
As a precautionary measure, a piece twice as big as the one required by the protocol was cut from the Shroud; it measured 81 mm × 21 mm (3.19 in × 0.83 in).
A strip showing coloured filaments of uncertain origin was discarded.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.The main part of the shroud does not contain these materials".He speculated that these products may have been used by medieval weavers to match the colour of the original weave when performing repairs and backing the shroud for additional protection. that radiocarbon measurements on the shroud should be performed blind seem to the author to be lacking in merit …
