Well, we all have to live with our own beliefs I guess. I will just repeat a quote from the last link I copied--with my boldings on a couple of sentences--and I'll leave it at that...

But let me assert that ad hoc, overreaching, counter-arguments to McCrone's conclusions--such as (1) some of the iron oxide particles came from blood iron, (2) most of the red particulate matter is from the blood on the Shroud, (3) most of the red particulate matter is "intimately associated with the image areas because shards of this material have broken off the blood areas and, since image area is always folded against image area, there occurred a translocation of the shards from the blood areas to the non-blood image areas," and (4) the presence of pigment particles on the shroud is due to paint chips falling off the frescoed ceiling and walls of the room use for the Shroud examination--are so far beyond the pale that they are a mockery of analytical thinking. Such explanations are pseudoscientific attempts to keep the possibility of authenticity alive in the minds of supporters who lack the ability to think critically. There is no blood on the Shroud: all the forensic tests specific for blood have failed (although some investigators unrigorously concluded that blood was present after conducting numerous forensic tests for iron, protein, albumin, etc., which came up positive because these materials are indeed on the Shroud in the form of tempera paint). Old blood is not bright red, and no amount of bilirubin can explain that away. Real blood mats on hair, and does not form perfect rivulets and spiral flows. Real blood does not contain red ochre, vermilion, and alizarin red pigments. Real blood and its organic derivatives have refractive indices much less than red ochre or vermilion, and they can be easily distinguished using Becke line movement under a light microscope. McCrone's examination of the red particles on the Shroud samples revealed no blood or blood derivatives

Here are McCrones comments:
"The suggestion that the 1532 Chambery fire changed the date of the cloth is ludicrous. Samples for C-dating are routinely and completely burned to CO2 as part of a well-tested purification procedure."
The Shroud of Turin
According to Dr. Walter McCrone and his colleagues at McCrone Associates, the 3+ by 14+ foot cloth depicting Christ's crucified body is an inspired painting produced by a Medieval artist just before its first appearance in recorded history in 1356. The faint sepia image is made up of billions of submicron pigment particles (red ochre and vermilion) in a collagen tempera medium. Dr. McCrone determined this by polarized light microscopy in 1979. This included careful inspection of thousands of linen fibers from 32 different areas (Shroud and sample points), characterization of the only colored image-forming particles by color, refractive indices, polarized light microscopy, size, shape, and microchemical tests for iron, mercury, and body fluids. The paint pigments were dispersed in a collagen tempera (produced in medieval times, perhaps, from parchment). It is chemically distinctly different in composition from blood but readily detected and identified microscopically by microchemical staining reactions. Forensic tests for blood were uniformly negative on fibers from the blood-image tapes.
There is no blood in any image area, only red ochre and vermilion in a collagen tempera medium. The red ochre is present on 20 of both body- and blood-image tapes; the vermilion only on 11 blood-image tapes. Both pigments are absent on the 12 non-image tape fibers.
The Electron Optics Group at McCrone Associates (John Gavrilovic, Anna Teetsov, Mark Andersen, Ralph Hinsch, Howard Humecki, Betty Majewski, and Deborah Piper) in 1980 used electron and x-ray diffraction and found red ochre (iron oxide, hematite) and vermilion (mercuric sulfide); their electron microprobe analyzer found iron, mercury, and sulfur on a dozen of the blood-image area samples. The results fully confirmed Dr. McCrone's results and further proved the image was painted twice-once with red ochre, followed by vermilion to enhance the blood-image areas.
The carbon-dating results from three different internationally known laboratories agreed well with his date: 1355 by microscopy and 1325 by C-14 dating. The suggestion that the 1532 Chambery fire changed the date of the cloth is ludicrous. Samples for C-dating are routinely and completely burned to CO2 as part of a well-tested purification procedure. The suggestions that modern biological contaminants were sufficient to modernize the date are also ridiculous. A weight of 20th century carbon equaling nearly two times the weight of the Shroud carbon itself would be required to change a 1st century date to the 14th century (see Carbon 14 graph). Besides this, the linen cloth samples were very carefully cleaned before analysis at each of the C-dating laboratories.
Experimental details on the tests carried out at McCrone Associates or the McCrone Research Institute are available in five papers published in three different peer-reviewed journal articles: Microscope 1980, 28, 105, 115; 1981, 29, 19; Wiener Berichte uber Naturwissenschaft in der Kunst 1987/1988, 4/5, 50 and Acc. Chem. Res. 1990, 23, 77-83.
Conclusion:
The "Shroud" is a beautiful painting created about 1355 for a new church in need of a pilgrim-attracting relic. |
