tests negative]." "Because the shroud and other very old linens do not give the vanillin test [i.e.test negative], the cloth must be quite old." "A determination of the kinetics of vanillin loss suggests that the shroud is between 1300- and 3000-years old. On the evidence that the radiocarbon date of the Turin Shroud was significantly affected by the 1532 fire.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.The radiocarbon date was thus not valid for determining the true age of the shroud." "As part of the Shroud of Turin research project (STURP), I took 32 adhesive-tape samples from all areas of the shroud and associated textiles in 1978." "It enabled direct chemical testing on recovered linen fibers and particulates".An Italian team at the Politecnico di Torino, a well respected Italian University, claims the powerful magnitude 8.2 earthquake, which occurred in Old Jerusalem in the year 33 AD, would have been strong enough to release neutron particles from crushed rock.According to scientists from Politecnico di Torino, radiation emissions caused by an earthquake may have confused carbon dating tests conducted in 1988 which suggested the cloth was only 728 years old, and therefore likely to be a forgery.FTIR identifies chemical bonds in a molecule by producing an infrared absorption spectrum.

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.Even allowing for errors in the measurements and assumptions about storage conditions, the cloth is unlikely to be as young as 840 years." "A gum/dye/mordant [(for affixing dye)] coating is easy to observe on... No other part of the shroud shows such a coating." "The radiocarbon sample had been dyed. Effects of fires and biofractionation of carbon isotopes on results of radiocarbon dating of old textiles: the Shroud of Turin.
