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 development in the 1970s of new techniques for radio-carbon dating, which required much lower quantities of source material, prompted the Catholic Church to found the Shroud of Turin Research Project (S. Also present were Cardinal Ballestrero, four priests, archdiocese spokesperson Luigi Gonella, photographers, a camera operator, Michael Tite of the British Museum, and the labs' representatives.
lack of blindness in the measurements is a rather insubstantial reason for disbelieving the result." (t)he Church must respond to the challenge of those who want it to stop the process, who would want us to show that the Church fears the science.that radio-carbon testing dated the shroud to a date of 1260-1390 AD, with 95% confidence.The official and complete report on the experiment was published in Nature.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.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: "The worst possible sample for carbon dating was taken." As part of the testing process in 1988, Derbyshire laboratory in the UK assisted the Oxford University radiocarbon acceleration unit by identifying foreign material removed from the samples before they were processed.These included an article by American chemist 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.Rogers took 32 documented adhesive-tape samples from all areas of the shroud and associated textiles during the STURP process in 1978. Luigi Gonella (Department of Physics, Turin Polytechnic University) on 14 October 1979, which Gonellla told him were from the Raes sample.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.On September 28, 1988, British Museum director and coordinator of the study Michael Tite communicated the official results to the Diocese of Turin and to the Holy See.In a well-attended press conference on October 13, Cardinal Ballestrero announced the official results, i.e.
