Carbon 14 dating and the shroud of turin
The human nature and nature of humanity that allows us as a mammal to have such relics to debate over is the true miracle.
In addition to the discovery of dye, microchemical tests - which use tiny quantities of materials - provided a way to date the shroud.
These tests revealed the presence of a chemical called vanillin in the radiocarbon sample and in the Holland cloth, but not the rest of the shroud.
The Shroud of Turin is much older than suggested by radiocarbon dating carried out in the 1980s, according to a new study in a peer-reviewed journal.
