Can some simple, natural process explain a doubly-superficial image?

When a cloth is dried on a line, impurities concentrate on both evaporating surfaces; however, more impurities will deposit on whichever surface dries faster. Any concentration of impurities can take part in the image-formation reactions. This can explain the "doubly­superficial" image.

Shroud Description

  • The cloth

    The Shroud is a single piece of linen cloth measuring about 14 feet by 3½ feet. The weave is a 3 over 1 herringbone weave. It is bloodstained and shows faint ventral and dorsal images of a man who, by the wounds that are visible, appears to have been crucified. He seems to be in burial repose.

    The bloodstains

    The bloodstains on the Shroud are composed of hemoglobin and give a positive test for serum albumin. Numerous tests confirm this.

    The images

    The Shroud's images are superficial and fully contained within a thin layer of starch fractions and saccharides that coats the outermost fibers of the Shroud. The coloration is a caramel-like product or the product of an amino/carbonyl reaction. Where there is no image, the carbohydrate coating is clear. There is also a very faint image of the face on the reverse side of the Shroud which lines up with the image on the front of the cloth. There is no image content between the two superficial image layers indicating that nothing soaked through to form the image on the other side.

    Until recently, it was widely believed that the images on the Shroud of Turin were produced by something which resulted in oxidation, dehydration and conjugation of the polysaccharide structure of the fibers of the linen itself. This has been shown to be incorrect. The coating, whether imaged or clear, can be reduced with diimide or removed with adhesive leaving clear cellulose fiber.

    The images as they appear on the Shroud are said to be negative because when photographed the resulting negative is a positive image.

    The Turin Shroud was examined with visible and ultraviolet spectrometry, infrared spectrometry, x-ray fluorescence spectrometry, thermography, pyrolysis-mass-spectrometry, laser­microprobe Raman analyses, and microchemical testing. No evidence for pigments (paint, dye or stains) or artist's media was found anywhere on the Shroud.
