matthias : “And that open mind should include Colin Berry’s decent scorch theory”
Reply from Ron (my italics):
“I approached Colin’s scorch theory with an open mind! But I don’t think his attempt was very scientific, especially since he never showed any proper results. As I believe I commented back then; “anyone can scorch a linen cloth, but doing so AND replicating the exact attributes of the image we find on the Shroud is two different things”. Colin never produced results at all, except some scorched images on cloth.”
Almost true, but not quite. I showed that scorch images are pseudo-negatives that respond to 3D enhancement (see banner above). I showed that they could be highly superficial, indeed confined largely to the crowns of the weave, as per Shroud, and that a single layer of onion epidermal cells just one cell thick is sufficient to protect underlying linen from conducted heat, pointed out the superficial location of reactive hemicelluloses in the primary cell wall, and the exothermic nature of hemicellulose pyrolysis that could account for half-tone properties and other peculiarities, offered a chemical explanation for why the Shroud image does not fluoresce under uv light, whereas the 1532 burn marks do (fluorescent benzenoid ring systems forming only at extreme temperatures for carbonisation as distinct from light scorching), and provided an explanation for the twin-track creases in the Shroud at chin and head level (scorched-in creases) and that a scorch can be produced with radiant as well as conducted heat, provided there is an opaque pigment present, e.g. charcoal.
But apart from that, no, I never produced results at all, except for some scorched images…
