They placed a linen sheet flat over a volunteer and then rubbed it with a pigment containing traces of acid. A mask was used for the face. The pigment was then artificially aged by heating the cloth in an oven and washing it, a process which removed it from the surface but left a fuzzy, half-tone image similar to that on the Shroud. He believes the pigment on the original Shroud faded naturally over the centuries.Not even close.
Now as to the data, reviewing the C14 info, and the previous botanical data should shed newer light on the Shroud's travels.
The skeptics will always call it a fake, those who have faith will always believe.
As for me. for the Shroud to be a fake would have taken an intimate knowledge of the implements used by the Romans at the time of Christ, the linen, weave, materials available, the method and tools for the abuse of the body depicted, and a volunteer to not only take the abject abuse, but die in the process. They would have to know bloodflow in both living and dead individuals, and the dynamics of crucifixion as practiced by the Romans.
And that is just to name a few things to believe it's a fake.
