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

The Shroud of Turin – let’s focus on that hemicellulose coating on the linen fibres … It could explain a great deal

Yes, hemicellulose is, I now believe, the answer. Each fibre in the yarn, or which there are reckoned to be some 200 per thread, comprises a core of physically and chemically resistant cellulose microfibrils, and the entire assembly is then … Continue reading
