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 rapid change in color from black to white at the margins of the scorches illustrates this fact." "Different amounts of vanillin would have been lost in different areas.

No samples from any location on the shroud gave the vanillin test [i.e.

In 1532, there was a fire in the church in Chambery, France, where the Shroud was being kept.

Part of the metal storage case melted and fell on the cloth, leaving burns, and efforts to extinguish the fire left water stains. In 1534, nuns sewed patches over the fire-damaged areas and attached a full-size support cloth to the back of the Shroud. The Shroud was moved to Turin in 1578, where it remains to this day.

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.

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. Journal of Archaeological Science, Volume 23, Issue 1, Pages 109-121. They comprise three tests; two chemical and one mechanical.

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.

1988 CARBON-14 TEST REFUTED The 1988 Carbon-14 tests done at Oxford, Zurich and Arizona Labs used pieces of the same sample cut from a corner (lower left of above pictures).1.
