Carbon dating level chemistry
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.
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.
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.
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.
