The separated grains then are allowed to deposit on aluminum discs in a thin layer of a few microns thickness which are placed at the bottom of individual flat-bottomed glass tubes.We prepared twenty discs for each sample, the whole discs were placed on the tray, using tweezers [15], which contain 48 holes, before measurement.To reach this goal many techniques were applied, since the initial ceramics study by Sayre and Dodson [6], such as X-ray fluorescence (XRF) [7, 8], proton induced X-ray emission (PIXE) [9, 10], and neutron activation analysis (NAA) [3, 5, 11, 12].We applied in our laboratory most of these techniques to study archaeological objects.This treatment revealed two main groups; the first one contains only the three samples M52, M53, and M54 from Mar-Takla site, and the second one contains samples that belong to Tel Jamous site (local).Analysis of archaeological ceramics can confirm the information recorded in historical documents, such as trade routes linking populations of different areas, and help to find out the chronology of events.We have selected four fragments from Tel Jamous site to determinate their age using thermoluminescence (TL) method; the results revealed that the date assigned by archaeologists was good.

The other aim was providing new additional data to the Syrian database.The data which consisted of the concentration of fourteen chemical elements have been treated statistically using two methods, cluster and factor analysis, to establish a categorization of the ceramics raw material source from Tel Jamous archaeological site.The chemical groups are assumed to present sources which could present the use of local material or production workshops.Strontium-90 (emitting beta particles) was used as the radioactive source, with a dose rate of 0.135 Gy/s.The annual dose was estimated from measurements of the radioactive elements U, Th, and K within the sample and soil and from cosmic rate.Establishing databases of Syrian ceramics, by using many techniques, was started a few years ago.The classification of ceramics based on typology is one of useful methods, but only when applied to whole or reconstructed objects [1, 2].
