Why are Shroud image fibres mechanically weaker than non-image bearing fibres? Pyrolysis of core hemicelluloses?

At the same time as composing a (serious) critique of the Rogers’ so-called “vanillin” clock (a misnomer if ever there was, as I shall be explaining shortly), I’ve been fielding objections on shroudstory.com to the scorch hypothesis. Serendipitously, I came … Continue reading

Why is the Shroud image so superficial, half-tone and striated? Is it on raised ribs of primary cell wall hemicellulose?

I posted this comment earlier today to an older  (September 1) thread on Dan Porter’s shroudstory.com site which appeared under the title: Paper Chase: An Alternate Hypothesis for the Image Color. It begins by quoting Porter (bold italics) who in turn … Continue reading

More thoughts on the fragility of image-bearing fibres on the Shroud of Turin

(This is a follow-on from my immediately preceding post) It’s one thing to invoke an impurity layer to account for image superficiality – or, alternatively – my preferred explanation – the primary cell wall (pcw).  (See two of today’s comments* … Continue reading

ColinB’s cunning plan for re-dating the Shroud of Turin

  Step 1: Obtain the go-ahead from the Shroud’s custodians to repeat that contested radiocarbon dating. Assure them that all samples will be taken from the  portion of linen that has the less photogenic DORSAL view. Step 2: select 20 … Continue reading

Can one bottle a scorch image? Could similar technology be applied to the Shroud image (scorch or otherwise)?

It’s amazing, is it not,  that  despite the Shroud having been the subject  of intensive study over several decades,  albeit with limited samples, we still don’t have any real substantial information as to the nature of the image?  At least … Continue reading

Charring, fluorescence and image-forming mechanisms. Beware Shroudology’s junk science and flawed logic…

Here’s what photographer- turned- self-styled scientist Barrie Schwortz, President of STERA (the so-called Shroud of Turin Education and Research Association  Inc) wrote back in February this year in attempting to dismiss my scorch mechanism:  “Every documented scorch on the Shroud … Continue reading

Sorry, Mr.Rogers (RIP), but you got it wrong about banding in the Shroud image ruling out linen modification

Quotation from Raymond Rogers’ 2004 (written one year before his demise): (Sorry, bad link: I’ve mislaid the correct one and will try to find it ASAP -since  I too need it). My italics: “Where darker bands of yarn intersect image … Continue reading
