One does not have to be acquainted with “Shroudology” for very long to pick up the received ‘doctrines’ (I hesitate to call it received wisdom). Prominent among those doctrines is the mantra that the Shroud image can’t possibly be a thermal imprint (“scorch”) from a hot template. Why not? Because the 1532 burn holes with their scorched margins fluoresce under uv light – a red colour we are told – whereas the Shroud image is ‘non-fluorescent’. What’s more, the entire fabric of the Shroud shows a weak fluorescence that is quenched in the regions where there is body image. Ipso facto, the Shroud’s body image cannot be a thermal imprint. Move along folks, nothing to see here.
Some of you may be familiar with physics-trained Hugh Farey, who has been doing experiments recently with scorching of linen, and use of an ultraviolet lamp to check changes in fluorescence that may or may not accompany scorching from hot metal.
Yesterday he kindly sent me photographs of some of his current experiments. In the next day or two I will display his photographs here, together with his accompanying comments. Any thoughts of my own regarding Hugh’s findings will appear as comments, provoked or unprovoked by others’ observations and conclusions.
From Hugh: “I’m sorry if the experiments look as if they were done on a bit of old floorcloth! The stripy patterns, particularly on the visible light photographs, are due to moire interference which is sometimes inevitable when compressing a photo for the web. The cloth is actually an ordinary 1/1 weave. Perhaps I should also say that all the photos were taken without flash, but the UV ones were exposure-enhanced to the maximum allowed in iPhoto.”

Sorry, Hugh – your picture transforms to ripples when I upload and insert. Don’t ask me why.
This was me playing around, Hugh, to show that an image was there, even at 130 degrees C, which could be made visible with extra contrast(see faint yellow- brown) But there’s the same ripple effect. Is it due to having sent a portfolio via email (image compression ?). Maybe try sending one of them single retaining as many of the original’s pixels?
Now that’s what I call a (bas relief) template. French physicians please note!
