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, Raymond Rogers stated in a 2005 article that he performed chemical analyses on these undocumented threads, and compared them to the undocumented Raes threads as well as the samples he had kept from his STURP work.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.It publishes many radiocarbon results, and since 1979 it has published the proceedings of the international conferences on radiocarbon dating.The Shroud of Turin, 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. 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 prime test, which should be completed at the detriment of other tests, if necessary.

group initially planned to conduct a range of different studies on the cloth, including radio-carbon dating. The six labs that showed interest in performing the procedure fell into two categories, according to the method they utilised: In 1982, the S. 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 a laboratory could thus identify the shroud sample.In a well-attended press conference on October 13, Cardinal Ballestrero announced the official results, i.e.that radio-carbon testing dated the shroud to a date of 1260-1390 CE, with 95% confidence.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.

and those "minute" fibers were identified as cotton by Peter South (textile expert of the Derbyshire laboratory) who said: "It may have been used for repairs at some time in the past, or simply became bound in when the linen fabric was woven. Shredding the samples would not solve the problem, while making it much more difficult and wasteful to clean the samples properly.
