Carbon dating of shroud of turin
The range of uncertainty for each test is high because the number of sample cloths used for comparison was low; 8 for FTIR, 11 for Raman, and 12 for the mechanical test.
The scientists note that "future calibrations based on a greater number of samples and coupled with ad hoc cleaning procedures could significantly improve its accuracy, though it is not easy to find ancient samples adequate for the test." They used tiny fibers extracted from the Shroud by micro-analyst Giovanni Riggi di Numana, who gave them to Fanti.
tested positive]." "The lignin on shroud samples and on samples from the Dead Sea scrolls does not give the test [i.e.
tests negative]." "Because the shroud and other very old linens do not give the vanillin test [i.e.
Iannone THE SHROUD AS AN ANCIENT TEXTILE The Shroud is a linen cloth woven in a 3-over-1 herringbone pattern, and measures 14'3" x 3'7".1988 CARBON-14 TEST REFUTED The 1988 Carbon-14 tests done at Oxford, Zurich and Arizona Labs used pieces of the same sample cut from a corner (lower left of above pictures).1.A Jan 20, 2005 paper in the professional journal Thermo Chimica Acta by Dr.Ray Rogers, retired Fellow with the Los Alamos Scientific Laboratory and lead chemist with the original science team STURP (the 1978 Shroud of Turin Research Project, involving approximately 35 scientists directly examining the Shroud for five days), has shown conclusively that the sample cut from The Shroud of Turin in 1988 was taken from an area of the cloth that was re-woven during the middle ages.Here are some excerpts: "Pyrolysis-mass-spectrometry results from the sample area coupled with microscopic and microchemical observations prove that the radiocarbon sample was not part of the original cloth of the Shroud of Turin.
