One was that the new methods of dating materials should be applied to determine relative not absolute chronology, that is, earlier versus later in the same test run -- absolute chronology in their view being virtually impossible to determine because of the multiple imprecisions to which C14 testing was subject.
To put this in another way, they framed their request in this manner because they did not believe that anything conclusive regarding the absolute dating of the Scrolls could be achieved with a technique as subject to multiple imprecisions as carbon testing was.
They are written with a carbon-based ink, from right to left, using no punctuation except for an occasional paragraph indentation. The Dead Sea Scrolls can be divided into two categories—biblical and non-biblical.
Fragments of every book of the Old Testament (Hebrew canon) have been discovered, except for the book of Esther.
Carbon dating the Dead Sea Scrolls refers to a series of radiocarbon dating tests performed on the Dead Sea Scrolls, first by the AMS (Accelerator Mass Spectrometry) lab of the Zurich Institute of Technology in 1991 and then by the AMS Facility at the University of Arizona in Tucson in 1994-95.
There was also a historical test of a piece of linen performed in 1950 by Willard Libby, the inventor of the dating method.
To check this evidence, radiocarbon ages of 14 selected scrolls were determined using accelerator mass spectrometry.
The calibrated radiocarbon ages agree well, except in one case, with the paleographic estimates or the specific dates noted on the scrolls.
However, as the quantity of 14 absorbed by all life fluctuates from year to year, the figure must be calibrated based on known fluctuation.In addition to the biblical manuscripts, there are commentaries on the Hebrew canon, paraphrases that expand on the Torah, community standards and regulations, rules of war, non-canonical psalms, hymnals and sermons.Introduction The first request for the application of up-to-date AMS carbon dating on Qumran documents was made by Professors Robert Eisenman of California State University Long Beach and Philip Davies of the University of Sheffield, England in a letter to Amir Drori, then Head of the Israeli Antiquities Authority, on May 2, 1989.The letter stemmed from their frustration at the denial of an earlier request in March 16, 1989 , addressed to John Strugnell and copied to Mr.Drori, to gain access to the Qumran parallels to the famous Damascus Document (CD) and the general situation denying access to unpublished Qumran materials to scholars not part of the "International Team or those favored for some reason by it.
