Multiple thermo-imprinted images from a single bas-relief template obtained as the trinket cooled down
Yes. I've given up on thermo-stencilling for a bit (see previous posts) and am now experimenting with bas-relief. So far I've merely repeated what John P Jackson of the STURP team and others have done - which was to produce a scorch mark on untreated linen with a heated bas-relief object (in this case a trinket I picked up while in Ghana). Yup, I know that the Turin Shroud is not a scorch mark according to the admirable Raymond N Rogers (RIP). But Rogers was not infallible - indeed I shall shortly be putting some of his experiments and conclusions under a fellow (bio)chemist's, er, microscope, and in any case Rogers only said it was not a scorch onto bulk fibres in linen. But that did not preclude the possibility that it was a thermal - or maybe chemical imprint onto a superficial layer of something else that was more thermo-sensitive than cellulose, as Rogers himself proposed. eg. starch, or simple hexose or pentose sugars.
However, experimental work will have to be put on the back burner for a while (literally). I am presently composing a critical overview of another paper that has been pushed under my blogging nose, namely that of Fanti et al on the use of computers to re-image the "true" (ho ho) ventral and dorsal ("front and rear") anthropomorphic dimensions of the image on the Shroud.
