Did Walter McCrone find paint on the Shroud of Turin?
According to the McCrone Associates web site, the . . .
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.” According to McCrone the image is made up of “billions of submicron pigment particles of red ochre and vermilion in a collagen tempera medium.
McCrone's conclusions are flawed. He may have found trace amounts of pigment particles (iron-oxide and mercury-sulfide) but not enough material to form a visible image. That is the conclusion of every other scientist who has studied the Shroud or fibers taken from the Shroud. McCrone's observations have not been successfully reproduced by anyone. No collagen tempera has been found. Spectral analysis proves, beyond a doubt that the images on the Shroud were not painted using paints that McCrone claimed or with any other known paint used in the Middle Ages.
It is important to note that McCrone did not publish his finding in peer-reviewed scientific journals, the normal way that scientists report scientific findings. He published his finding a Microscope, a magazine that he edited and published.
Walter McCrone was a world renowned microscopist. He was a true scientist and he knew his craft well. He founded McCrone Associates in Chicago.
