Shroud Maillard hypothesis.
The present proposal is not to study the Maillard reaction at all. In Shroud circles the expression “the Maillard reaction” has come to be used as a general term for Ray Rogers’ claim that the image has been formed by a Maillard reaction and, more surprisingly, that it involved gases that retained, within their gaseous state, information about some physical characteristics eg. the shape, of their source. His claim is based on experiments that he carried out simulating the conditions with the tomb.
The work proposed is designed to test only the latter part of this claim by Rogers which is quite a surprising claim ie. that a clear image (comparable with the image on the Shroud) can be made on a recipient surface by gases that rise in a thermal current and retain, during their movement, the details of the surface, (wounds, fingers etc) from which they were released. This claim will be tested by the accuracy of the image they generate on a reactant surface. At the same time it will test to what extent any simultaneous diffusion within the gas phase obscures the image. This is as far as the proposal goes.
This high quality image is an essential prerequisite before we go on to study what reaction has caused the image. If we do get the high quality image may some people may still need verify that it has the same chemical composition as the image on the Shroud. This would then lead into studies of the possible reactions that might have formed the image, including the Maillard reaction.
