Yes, here in a series of pictures, is an attempt to scorch linen so severely in my new “fabric on top” mode that folk will straight away dismiss it as invalid – producing an image with none of the subtlety of the Man on the TS. However, the cognoscenti reading this will know that linen is quite hard to scorch severely – far more so in my experience than cotton – so one has botany on one’s side, so to speak, in doing what otherwise might be seen as a perverse exercise in model-building masochism.
The microscopy is to be the subject of a separate posting, to follow on from this shortly.
Update: now added. Click on link below to see the appearance of that intensely-scorched arm area under the microscope. Do the fibres look “charred” or merely coloured/roasted/scorched etc – as might be the various descriptions of the Shroud image?
