Carbon 14 dating of the shroud of turin
A linen produced in 1260 AD would have retained about 37% of its vanillin in 1978...
The Holland cloth, and all other medieval linens gave the test [i.e.
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".
The radiocarbon sample was thus not part of the original cloth and is invalid for determining the age of the shroud." "A significant amount of charred cellulose was removed during a restoration of the shroud in 2002." "A new radiocarbon analysis should be done on the charred material retained from the 2002 restoration." 2. The chemical tests were done with Fourier Transform Infrared Spectroscopy (FTIR) and Raman spectroscopy, examining the relationship between age and a spectral property of ancient flax textiles.In 1532, there was a fire in the church in Chambery, France, where the Shroud was being kept.
