Shroud of Turin Facts Check  > Weave of the cloth showing image color

Close up view of the Shroud cloth. Each thread is hand spun from cellulose fibers from flax. Notice golden color on some of the fibers. Spectral and chemical tests show that fibers are coated with a thin carbohydrate file. In places this film has turned a golden-brown color that seems to be the result of caramelization or a Maillard reaction.

The coating is superficial. It is only found on the outermost fibers at the crown of the threads. Pulling back individual fibers reveals that there is no image color below the outer threads.

Face on Shroud as photographed

Face on the Shroud as it appears when photographed. This is the negative.

Gum encrusted fiber

Gum encrusted cotton fiber found only in the carbon 14 sample area and not elsewhere on the cloth.

Spliced thread

Close up view of spliced thread in the carbon 14 sample area showing that what was tested was likely a repair and not original cloth.

Mordant lakes

Photomicrograph, gum is swelling and slowly detaching from the fibers and alizarin mordant lakes can be seen. Yellow dye is in solution. Further evidence of repair.

Single fiber up close

Phase-contrast microscopy of a single image fiber. Image is a reddish-brown caramel-like complex carbon bond, a chemical change within a super thin coating of crude starch on the fabric's outermost fibers. It is not paint or any kind of applied pigment. It is likely caused by bodily amine vapors reacting with saccharides in the starch.

Face as it appears on Shroud

This is how the face appears on the cloth.

Second face found on back of cloth

Second face image recently discovered with image analysis technology. This a a computer enhanced view. It matches the face on the front of the Shroud. The images are doubly-superficial meaning that nothing soaked through.
