Secret to This Dead Sea Scroll’s Incredible Preservation — And Inevitable Destruction — Could Be Salt

The Temple scroll is the best protected of each of the 900 Dead sea Scrolls, and specialists just got one bit nearer to making sense of its mystery.

 

The Dead sea Scrolls are a wonder. Covered for around 2,000 years under heaps of flotsam and jetsam and bat guano in a chain of collapses the Judean desert, the accumulation of about 1,000 divided original copies incorporates scriptural writings, old schedules and early galactic perceptions.

 

Among these strange antiques (a large number of which are presently simply worn out pieces of material) one flawlessly protected record sticks out. The Temple scroll, named for its depiction of a Jewish sanctuary that was rarely assembled, is one of the longest (it extends 25 feet, or 8 meters, in length), most slender and simplest looks to peruse.

 

Why, out of thousands of blurred sections found in the Judean caverns, has the Temple scroll fared so well following two centuries? In another investigation distributed today (Sept. 5) in the diary Science Advances, scientists endeavored to discover by examining a bit of the material utilizing each X-beam and spectroscopic apparatus available to them. They found that the parchment did in fact have something its antiquated kin did not — hints of a salty mineral arrangement not present in some other recently considered parchment, nor in any of the caverns or in the Dead sea itself.

 

As indicated by the specialists, the nearness of these minerals demonstrates that the Dead sea Scrolls were created utilizing a noteworthy assortment of methods — and, all the more significantly, the find could likewise educate the manner in which these parchments are protected later on.

 

“Understanding the properties of these minerals is especially basic for the advancement of appropriate protection strategies for the safeguarding of these priceless recorded archives,” the specialists wrote in the investigation.

 

Earlier investigations uncovered that the Temple scroll was not normal for most other Dead sea pieces, in that it was made out of a few unmistakable layers: a natural layer, made of the creature skin that filled in as the material’s base; and an inorganic layer of minerals that may have been scoured on during a material “completing” process. While the majority of the Dead sea Scrolls come down to creature skins — typically taken from dairy animals, goats or sheep before being scratched perfect and extended on a rack — few indicated proof of completing, the analysts composed.

 

To make sense of what this inorganic layer was made of, and whether it was scoured there purposefully, the group examined a part of the Temple scroll utilizing X-beam sweeps and Raman spectroscopy — a procedure that uncovers the concoction arrangement of a substance by observing how laser light dissipates off different compound components. They found that the parchment was covered in a blend of salts produced using sulfur, sodium, calcium and different components. In any case, these salts did not coordinate components found normally on the cavern floor or in the Dead sea, precluding a characteristic cause.

 

The Temple scroll, the creators closed, more likely than not been done in a bizarre manner that was not utilized on some other realized Dead sea Scrolls. It’s conceivable that this salt covering has added to the Temple scroll‘s exceptionally well-protected appearance, the group composed — at the same time, in the mean time, it could likewise be a fixing in the parchment‘s inevitable demolition. Since the salts distinguished on the parchment are known to drain dampness out of the air, their essence could “quicken [the scroll‘s] debasement” if not put away appropriately, the creators said
