Didn’t a famous art forensics guy eith STRP say it was painted?

Yes. However, he was not an official member of STURP, he did some work for them under contract.

Walter C. McCrone, a microscopist, claimed that he found Red Ochre (Iron Oxide) and Vermilion (Mercury Sulfide) paint on the Shroud. He also claimed that there is no blood on the Shroud. No other scientist, examining the same materials that McCrone examined, has found what he claimed. World renowned experts in blood fractions, blood remnants, and porphyrins have examined the blood stains on the Shroud and stated in peer-reviewed scientific journals that the blood stains ARE extremetly old blood products and blood derivatives. They even reported that the blood stains gave positive results for immunoassay testing for human/primate blood.

McCrone refused to submit his work to peer-review until ten years later, and originally published his 'findings' only in his own vanity publication The Microscope, in direct violation of his contract with the Shroud of Turin Research Project scientists. Even McCrone's own employee, an electron microscope specialist, rebutted McCrone's claims after putting the samples under his EM.

No evidence for pigments (paint, dye* or stains) was found anywhere on the Turin Shroud. Other far more specific scientific tests including ultraviolet spectrometry, infrared spectrometry, x-ray fluorescence spectrometry, thermography, pyrolysis-mass-spectrometry, laser microprobe Raman analyses, and microchemical testing, have shown there are no pigments on the Shroud that are significantly associated with the image areas. What small amounts of such pigments are found appear to be randomly distributed environmental contaminations or contaminations caused by the pressing of painted copies to the original shroud to imbue them with a holy connection, strewn across the Shroud unrelated to image or non-image areas. (I have asterisked the comment on "dye" above because dyes have been found only in one location on the Shroud: half of the 1988 Carbon Test sample is composed of dyed Cotton instead of the un-dyed Linen that makes up the other half of the sample and the rest of the Shroud's main body.)

We now know exactly what the image is composed of... and it is not Red Ochre or Vermilion. It is a polysaccharide, a form of caramel, formed in the starches left behind by the retting process (a technique to soften Linen) and its washing in Soapwort. One modality of formation demonstrated is the formation of the caramel substance, a meloiden

I was checking the spelling of melanoidin, when I accidentally clicked post... To continue... One modality of formation demonstrated is the formation of the caramel-like substance, a melanoidin, is the amino/carbonyl reaction that occurs to the starches when in the presence of gases that exude from a newly dead body... putrescine and cadaverine. There are other chemicals and physical processes that will produce the carbohydrate caramel-like substance that makes up the Shroud's image... including heat (cooking is a Maillard reaction that will produce similar substances).

It certainly is NOT PAINT... and completely falsifies McCrone's claim of finding that the image was a "beautiful medieval painting."

I saw on another post that Rogers also published his article in ajournal he helped to found. Is that true?
