And Bip - what new Shroud news have you heard lately?
Well since you mentioned it Philip
you do know my weakness
I’ve yet to look at the X-ray method they did to determine that the shroud dated to 2000 years ago .

The new X-ray analysis is said to be more accurate and less destructive than radiocarbon dating.
In 1988 radiocarbon dating of the Shroud of Turin found that the relic many faithful believe to be the burial linen of Christ originated about 700 years ago. While the study suggested the shroud was not authentic, it has done little to abate the faith of those thousands who make pilgrimage to Turin to venerate the relic. Now, a new dating technology has placed the fabric within the time of Christ.
WAXS
The study was conducted by Dr. Liberato de Caro of Italy’s Institute of Crystallography of the National Research Council, in Bari. Dr. de Caro has employed a method known as “Wide-Angle X-ray Scattering,” or WAXS, which measures the natural aging of flax cellulose and converts it to time since manufacture.
The process has several key features that make it more desirable than radiocarbon dating, not least of which that it is completely non-destructive to the samples. Furthermore, the size of the sample required for WAXS is much smaller, requiring just a portion of cloth approximately 0.5mm x 1mm.
Carbon-14 inadequacy
In his report, published on the website of Italy’s Department of Chemical Sciences and Materials Technologies, de Caro pointed out a few flaws with dating by Carbon-14 analysis. He noted that textile samples can easily become contaminated with substances that could skew its results. He wrote:
“Molds and bacteria, colonizing textile fibers, and dirt or carbon-containing minerals, such as limestone, adhering to them, in the empty spaces between the fibers that at a microscopic level represent about 50% of the volume, can be so difficult to completely eliminate in the sample cleaning phase, which can distort the dating.”
De Caro noted that fabric can even become enriched with new Carbon-14 samples. At this point, it would become hard to identify if carbon dating measured the original fabric, or a layer of carbon that was accumulated over time.
