We have therefore developed a method to measure the natural aging of flax cellulose using X-rays and then convert it into time elapsed since fabrication. Natural aging depends only on ambient temperature and relative humidity. As the number of shocks increases, always of the same intensity, the average length of the spaghetti decreases over time, until it reaches a minimum length.Ī similar thing happens to the polymer chains of cellulose which, like spaghetti but with a section on the scale of a billionth of a meter, gradually break over the centuries due to the combined effect of temperature, humidity, light and the action of chemical agents in the environment in which they are found.

A macroscopic example of a fabric microfiber is like that of a bundle of spaghetti: at first they all have the same length, but if you subject the bundle to accidental shocks, the more the shocks increase, the more the spaghetti breaks. According to Christian tradition, it is the burial shroud that would have wrapped the body of Jesus after his crucifixion.įor about 30 years, I have been using investigative techniques on the scale of atoms, in particular through X-rays, and three years ago we developed a new method for dating samples taken from linen fabrics. The Shroud of Turin is the most important relic of Christianity. De Caro, please could you share with us in layman’s terms your findings regarding the Holy Shroud of Turin? In this April 13 email interview with the Register, De Caro, who has been investigating the Holy Shroud for 30 years, explains more about the discovery, why he believes the X-Ray technique is superior to carbon dating for determining the age of fabric fibers, and discusses other recent discoveries that also point to the Holy Shroud’s authenticity.ĭr. They concluded that their peer reviewed research shows the Holy Shroud is compatible with the hypothesis that it is much older than seven centuries old - the conclusion reached in 1988 using carbon dating techniques - and is around 2,000 years old. Working with a team of other researchers, Liberato De Caro of Italy’s Institute of Crystallography of the National Research Council in Bari used a “Wide-Angle X-ray Scattering” method to examine the natural aging of cellulose that constitutes a sample of the famous linen cloth.

An Italian scientist is claiming a new technique using X-ray dating shows the Holy Shroud of Turin to be much older than some scientists have stated, and that it does in fact coincide with Christian tradition by dating back to around the time of Christ’s death and resurrection.
