From Archaeology to Archaeometry Trans-disciplinary Research of our Cultural Heritage
Jan Gunneweg (Ph.D. in Archaeometry and Drs (M.A)in Biblical
Sciences) has been over 38 years in Archaeometry, first as a Senior Staff member in the former
Archaeometry Unit of the Institute of Archaeology at the Hebrew
University in Jerusalem, and since then as a member in Qumran Trans=Disciplinarity with the application of analytical techniques to Qumran Archaeology and its bio- and material cultures identification and conservation. Since June 2009, he represents Israel and the Hebrew University in COST-Action D42 (Cooperation in Science and Technology). In this context, special attention has been
paid to the Dead Sea Scrolls (parchment and ink)in the light of the already established provenience of Qumran pottery. Further attention has been focused on
Qumran textile dating and its identification as well as the use of
organic dyes of textiles.
The title "Trans-disciplinary Research" encompasses analyses in
all different domains as archaeology, art, history, optics, physics, social sciences and chemistry. All these are
at present applied to a variety of remains of our cultural heritage.
These disciplines are used to understand ancient and present cultural
remains, as well as to preserve them for the future generations.
Since September 2007 Gunneweg was a fellow at NIAS, the Netherlands Institute of Advanced Studies [Dutch Academy of Sciences], with a workshop at the Lorentz Center of the Institute of Physics and Mathematics of Leiden University, Netherland. br>
Archaeometry i.e. measurements applied to archaeology--borrows its name from the science magazine Archaeometry founded at Oxford University (UK) during the early nineteen-fifties.
Archaeometry is a collective name for an analytical approach to define
archaeological cultural remains by means of Natural Sciences to obtain
quantitative and qualitative measurements in the domain of seven
important fields in Archaeology:
IDENTIFICATION of materials by chemistry, optics and mineralogy & written texts by epigraphy and palaeography
PROSPECTION (The research of Where and What to excavate)
CHRONOMETRY (Techniques for Dating architectural, art and archaeological finds)
PROVENIENCE (The search for the Site where an artefact was manufactured)
ENVIRONMENTOLOGY (The study of ancient climatic, volcanic and geological changes in a given area at a given time span)
BIOSPHERE (The research into the Palaeo-ethnic-botany and Zoo- and Anthropo-archaeology)
RESTORATION-CONSERVATION (The study of how to restore and conserve ancient artifacts belonging to our cultural heritage)
Personal
interest is primarily focused on the establishment of the chemical
composition of ancient pottery through Instrumental Neutron Activation
Analysis (hence INAA) to learn W H E R E pottery was manufactured (the
Provenience, Provenance or Origin). This may help the
archaeologist/historian in her/his search for the routes that pottery
traveled (the Trade) and H O W ancient pottery was made (the Technology).
Hence,
specific ancient interregional Trade Relations, Trade Routes, perhaps
Colonization and Migrations of families, tribes and masses are
potentially being traced through the provenance of their artifacts
Also the ancient pottery MANUFACTURE TECHNOLOGY
may be studied in the light of the chemical compositions obtained by
INAA and may further be complemented by thin
sections from analyzed pottery (Petrography) and Thermoluminescence dating combined with Magnetic Susceptibility. One may be able to tell how a
specific potter levigated and tempered raw clay that he used to
model a pot and what was the firing temperature in the kiln, thereby providing
important information about the technology that ancient man used.

The Qumran May 22-23 Meeting in Jerusalem
Meeting of the Cost G8 Action and the Hebrew University on Bio- and
Material Culture research of Qumran's Dead Sea Heritage in connection
with the Preservation of Europe's Cultural Heritage. The meeting was
scheduled as a cooperation between scholars who maintain the cultural
heritage as art historians, archaeologists and conservators, as well as
analytical scientists, as physicists and chemists, who perform non- or
minimal destructive analytical testing.

A Map of Israel
with Sites from where ancient pottery has been analyzed by Neutron
Activation Analysis (corresponding to the list of the Abstracts above)
The Mugrabi Gate near the Wailing Wall esplanade towards the western Temple Precinct wall.
At the left the golden Dome of the Rock. In the middle, the temporary
bridge from the Wailing Wall esplanade to the Gate of the Mores. On the
right the excavations in progress to save the already excavated area
from a dangerous landslide toward the North as well as the South. The
style of the future bridge is still under discussion, due to the danger of collaps. The excavations
aren't.
Ostracon with early Proto-Caananite script (15x15 cm), found by Y.
Garfinkel at Qeiyafa (the Ella Valley) mentioning the words Judge,
King, Servant and "don't do" (as in the Ten Commandments). In Hebrew, the
words are: Shofet, Melekh, Eved and al-ta'ase, respectively. The date
of the ostracon was established by radiocarbon dating of the organic
contect in which it was found. Thermoluminescence dating of the shard
itself will give the age of the pot and not necessarily that of the
writing. The faint script is not very promising for either HPLC
composition-identification or Raman Spectroscopy and its subsequent
dating by C14. The ostracon was analyzed by Jan Gunneweg for INAA to learn the origin of the letter A caveat is in its place here. Petrography proved that the potshard was made in the Lachish area. INAA, however, could NOT find a statistical match that would prove that the shard was indeed of the Lachish area, in spite of the fact that we have a lot of INAA data on our two databanks, the Hebrew University and Bonn laboratories. It is, therefore, suggested to get more analyses performed by INAA to realy prove the proto-Canaanitic script provenience. It is also suggested to get a precise date for the ostracon based on the shard itself and not that much on its organic material context, which was performed by radio-carbon dating.
On his 1989 Sabbatical at the LBL in Berkeley, Gunneweg got a glimps of the Extinction theory of the dynosaur by an astroid as Louis Alvarez suggested. This was subsequently proved by iridium measurements performed on 2.5 cm thick clay layer that was deposited allover the world. Schematically, this is rendered in the following site the K-T Boundary (Cretacious-Tertiair). This disaster was the end of the Dynosaur population. more than 65 million years ago.

Iz Perlman commemorated.
Iz Perlman founded the Archaeometry Unit for Neutron Activation
Analysis at the Hebrew University in Jerusalem in 1973 and headed it
until his retirement in 1983. In 1991, he died un untimely death. Lee,
his spouse, died in 2005.

Umm a-Shakef is a small village with houses abandoned somewhere in 1850 during the Ottoman period. The village covers a wide restrict that is filled with abandoned homes and hand-dug water wells, sometimes more than 20 meter deep. Umm a-Shakef had a mosque and also a church, although the latter is a remain of the Late Byzantine period. The only remain visible is the very end of a pillar that robbers could not take home, although they tried hard.

A Caveat for the 2000 year old date from Masada that suddenly grew again
In
June 2005, a date kernel put in soil started to grow again after 2000
years having laid around in the Masada fortress in Israel where it was
picked up. One should be aware of the
fact that every tourist who visits the Dead Sea area at present, first
visits either En Gedi or Qumran and then Masada. In the local souvenir Qumran shop
adjacent to the excavations, one sells dates that are grown there or in
En Gedi. Kernel spitting tourists over the past 50 years could have
dropped a kernel at Masada that originated from the date-selling
tourists centers and such a kernel would, of course, grow again,
because it has been around for half a century at the most. Just that one is aware of date_growing_wonders in Masada Lately, there are records that the kernel was dated by C14, of which the original news did not mention anything
An additional caveat
is directed to all kind of seals, palaces and ostraca that are found in
Israel during the past 3-6 years. They all have in common the
assumption that they are certainly of the Iron Age I period and prove
that David had his palace in Jerusalem, that personal king's seals
point to kings mentioned in the Bible, whereas the latest find, an
ostracon, shows the name of Goliat written in a language that is similar to that of
the Philistines, called "Lydian" or pre-Hebraic. However, first, no
archaeologist has ever found the remnants of a "Philistine language"
except for a single seal with some signs on it, whereas we are also
begged to believe that the non-semitic words "'alot" and "lat"
indeed mean Goliat. And all this because of the urge to prove that the
biblical story of Goliat is not a myth. Sic! During the March-2006
Archaeological Congress in Jerusalem, one explained
that the inscription must be dated to the Iron Age II and that it means
something as Goliat-alike, as if the name lives on in later periods.
The next Caveat
concerns the fact that lately too many finds appear too sudden in a too
small territory of Israel in the hands of too few people to prove too
vague historical evidence from holy writings that, in fact, can do
without all these new finds. The Newsmedia are out to get first-hand on
all these inventions, whereas serious scientific studies of artifacts are
considered "a big bore" and, thus, never hit any Evening News.
Still another Caveat concerns the tomb of Jesus' entire family that only has been revealed to National Geographic with the help of the maker of 'The Naked Archaeologist'.
The next item is the Japanese capsule that after 7 years returned to Earth on June 14 2010 containing dust from the astroid belt that is about 860 million km from our Earth.I hope that the elemental analyses will be done by competent scholars because we need quantitative data. From the other side, it could be that the dust contains elements that are unknow here and for that one needs people who are able to differentiate between different elements of isotopes with interfering peaks in astroid dust that leaves traces that only people as Iz Perlman (my colleague for 15 years), Glenn Seaborg, Louis Alvarez, all deseased, but also Frank Asaro with a blessed long life at NLBL Berkeley are able to take apart by using techniques such as INAA and Alvarez-Coincidence Spectroscopy.
