...Matthews and Ayalon based on their research on stalagmites in a cave near Jerusalem, where isotopic data showed rainfall and surface temperatures over many centuries, they concluded that the climate in the past 2,000 years could not have produced the patina on the ossuary. As they wrote with Professor Yuval Goren - another prosecution witness and professor of archaeology at Tel Aviv University - in the Journal of Archeological Science in 2004, "the patina covering the letters was artificially prepared, most probably with hot water, and deposited onto the underlying letters." The article states: "There is no evidence for the existence...
Scientists are unsure exactly how the patina is formed but most agree it is composed of deposits of solid calcium carbonate that come by way of rain or groundwater. It can contain particles added by wind and perhaps biological. Additionally, depending on the levels of acidity, it may also involve a chemical reaction with the surface of the object. Some scientists say the process is similar to the way stalagmites grow in caves; others disagree...
Testifying for the prosecution, Miryam Bar-Matthews and Avner Ayalon from the Geological Survey of Israel recorded isotopic values as low as -10.2 permil (parts per thousand) in patina found within the inscription on the ossuary. (It is believed that the lower the number permil, the wetter the season was when it was created.) "The patina could not have been created in the Judean Hills or the surrounding area in a natural way," Bar-Matthews told the court in October 2007. With the exception of one letter in the word Yeshua ("Jesus"), she said, "the patina in the other letters...
...amazing - it blows my mind," Kronfeld told TIME. "The findings in this study stand in complete contradiction to the assumptions presented by Ayalon and Bar-Matthews, and shed new light on the theory they presented to the court. They not only undercut their own arguments for determining that the patina on several items was not natural but rather quite the opposite. These data can support the authenticity of the items...
...Matthews, however, argues the data from her later study are "irrelevant" to the ossuary trial. She and her colleagues say that the very low values representing wet seasons were "noise" that should not be taken in isolation since patina takes many years to form. Patina's isotopic value would represent an average figure, not just the low winter results. "It's like comparing tomatoes and gloves," Bar-Matthews told TIME. "There is no scenario where we can get light isotopic values below -6 permil also in Jerusalem under natural conditions...
