Scorching Onion Skins

I want to call your attention to an interesting discussion going on over at Colin Berry’s site in his posting, … ‘Troll Central’ by any other name (beginning with a comments by Thibault Heimburger on March 3).

First, Thibault wrote:

Colin,

Can you explain step by step your onion experiment ? I am not sure to understand well, but I see no connection with the scorch hypothesis on the Shroud.

Colin Responded:

I’m a little surprised I have to explain (all over again) what to me seems self-evident. Never mind. Let’s start again.

And it goes from there. For more on the subject see, Modelling the image of the Turin Shroud – an interrupted experiment using onion epidermis – just one cell thick, a posting on Colin’s blog from two years ago.
