Flaws of carbon dating

He stated that his analysis showed: "The radiocarbon sample contains both a gum/dye/mordant coating and cotton fibers.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. group and the candidate laboratories turned into a P. However, in a 1990 paper Gove conceded that the "arguments often raised, … that discarding the blind-test method would expose the results – whatever they may be – to suspicion of unreliability.

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.In 1988, scientists at three separate laboratories dated samples from the Shroud to a range of 1260–1390 CE, which coincides with the first certain appearance of the shroud in the 1350s and is much later than the burial of Jesus in 30 or 33 CE. Samples were taken on April 21, 1988, in the Cathedral by Franco Testore, an expert on weaves and fabrics, and by Giovanni Riggi, a representative of the maker of bio-equipment "Numana".The idea of scientifically dating the shroud had first been proposed in the 1960s, but permission had been refused because the procedure at the time would have required the destruction of too much fabric (almost 0.05 sq m ≅ 0.538 sq ft). P.), which involved about 30 scientists of various religious faiths, including non-Christians. Testore performed the weighting operations while Riggi made the actual cut.The official and complete report on the experiment was published in Nature.As reported in Nature, Professor Bray of the Instituto di Metrologia 'G.
