Another evidence the Raes corner is not representative of the shroud is the Quad Mosaic imaging.
These color images should be interpreted as chemical composition maps. We
don’t know from the images what these chemicals are, only that they are not
the same everywhere. The same color in two locations indicates a likelihood that the
same chemistry exists at both locations.

So, chemically, the Raes corner is an anomalous section of the shroud. This is another clue why the C-14 dating is suspect. I’ll get into the details of that later when discussing theories why the C-14 has a medieval date.
