The shroud of turin carbon dating results
Following in-depth study of the surviving sample with the two proven methods of stereoscopic microscope work (to re-create the relief) and fluorescence, the researcher brought out several key points: first, the fabric is almost exclusively linen, hardly contaminated with any cotton fibres; it also has been subjected to no coatings or dyes.Next, the sample was indeed taken from the original part of the 4-metre-long shroud.
They aim to finally halt the steady criticisms since the dating that suddenly dashed the hopes of those touting the cloth's authenticity; it is claimed that it is the very shroud in which the body of Jesus Christ was wrapped after his crucifixion. The italian translation of the article by Sciences et Avenir. Timothy Jull, a long-standing figure in the story and in a privileged position for playing the part, today brought out major artillery…12.39 milligrams of linen, measuring only 0.5 cm by 1 cm."The fact that the vanillin cannot be detected in the lignin on the Shroud fibres, Dead Sea scrolls linen, and other very old linens, indicates that the shroud is quite old (...). What authenticity proponents have claimed has been rescued from the flames !Obviously, by making these claims the American chemist insults two top specialists on ancient fabrics – including the late Frenchman Gabriel Vial of Lyon's Musée des Tissus et des Arts Décoratifs – who carefully selected the area to cut out for the 1988 dating, from a spot far from both the rewoven and burned areas. Jacques Evin, then director of the université de Lyon radiocarbon dating centre, who took part in the protocol drafting, rages : "vanillin reduction is not regular over time and depends too much on moisture and temperature factors to be usable criteria!A study conducted on a sample of the Shroud of Turin confirms that the cloth dates from the Middle Ages.This ends polemic claiming specialists had previously dated the cloth with a sample taken from a part of the shroud rewoven in the Middle Ages.As he explained to Sciences et Avenir, it is "a piece of the shroud sample, which his Tucson laboratory received on 14 April 1988” - which he had cut, set aside and assumed something of a caretaker role for.
For the first 1988 analyses, the Vatican had permitted only a few milligrams of the shroud to be taken for analysis by three laboratories, in Tucson (USA), Zurich (Switzerland) and Oxford (England).
Some scientists and atheists delightedly insist the shroud is a "fake", whereas the dating does not necessarily mean that and intentions cannot be concluded or even physically measured.
Those claiming the shroud's age and authenticity are overwhelmed with astonishment, strong emotion and soon anger.
This dye was alizarin dye, extracted from the madder root, and used in Italy only from 1291; it would indicate that the dated parts had been stained later to ingeniously hide the piecemeal reweaving work on the original shroud : he triumphantly declared to the BBC. Rogers also measured vanillin levels, a natural breakdown product of the lignin present in flax; this vanillin content declines over time.
The test was negative for the adhesive-tape fibre samples from the shroud's overall surface, but positive for the Raes sample, in the area next to the C14 sample as well as on the Holland linen.
Only part of the sample entrusted to the American laboratory was destroyed in the dating process, however; a small part was preserved, Jull revealed today. Freed, specialised in fabrics from archaeological periods, he explains her microphotography analysis in detail.
