Radiocarbon dating shroud examples of male profiles for dating sites
These dimensions correlate with ancient measurements of 2 cubits x 8 cubits - consistent with loom technology of the period.
The finer weave of 3-over-1 herringbone is consistent with the New Testament statement that the "sindon" (or shroud) was purchased by Joseph of Arimathea, who was a wealthy man.
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.
tested positive] for vanillin wherever lignin could be observed on growth nodes.
The disappearance of all traces of vanillin from the lignin in the shroud indicates a much older age than the radiocarbon laboratories reported." "The fire of 1532 could not have greatly affected the vanillin content of lignin in all parts of the shroud equally. therefore, the unscorched parts of the folded cloth could not have become very hot." "The cloth's center would not have heated at all in the time available.
The spectra produce a profile of the sample, a distinctive molecular fingerprint that can be used to identify its components.
Raman Spectroscopy uses the light scattered off of a sample as opposed to the light absorbed by a sample.
Riggi passed away in 2008, but he had been involved in the intensive scientific examination of the Shroud of Turin by the STURP group in 1978, and on April 21, 1988 was the man who cut from the Shroud the thin 7 x 1 cm sliver of linen that was used for carbon dating.
These tests were carried out in University of Padua laboratories by professors from various Italian universities, led by Giulio Fanti, Italian professor of mechanical and thermal measurement at the University of Padua's engineering faculty.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.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.Dyeing was probably done intentionally on pristine replacement material to match the color of the older, sepia-colored cloth." "The dye found on the radiocarbon sample was not used in Europe before about 1291 AD and was not common until more than 100 years later." "Specifically, the color and distribution of the coating implies that repairs were made at an unknown time with foreign linen dyed to match the older original material." "The consequence of this conclusion is that the radiocarbon sample was not representative of the original cloth." "The combined evidence from chemical kinetics, analytical chemistry, cotton content, and pyrolysis-mass-spectrometry proves that the material from the radiocarbon area of the shroud is significantly different from that of the main cloth. John Jackson and Propp in 1998, which replicated the famous Fire of 1532, demonstrated that the fire added carbon isotopes to the linen.
