PRODUCTION TECHNOLOGY OF IRON AGE POTTERY FROM JNENEH AND TELL ABU AL-KHARAZ, JORDAN
Abstract:
The main purpose of this preliminary study is to establish the relationship between the mineralogical and chemical homogeneity of
Iron Age pottery vessels from Jneneh in North-Central Jordan and
Tell Abu Al-Kharaz in North-West Jordan, as well as to investigate
the technological level of production of these vessels found at the
two sites. Potsherds were subjected to examination using X-Ray
diffraction (XRD), Polarized light microscopy (PLM) and X-Ray
fluorescence (XRF), in order to determine the major and minor
elements, as well as the mineral content of these potsherds. The
results showed high homogeneity in chemical and mineralogical
composition in Jneneh potsherds, and this indicates that the mother
pottery vessels were manufactured using the same source of raw
materials and the manufacturing techniques were not altered with
time. Contrarily, high differences in chemical and mineralogical
compositions were observed in Tell Abu Al-Kharaz potsherds,
leading to the expectation that Tell Abu Al-Kharaz samples were
manufactured using different sources of raw materials. The
presence of primary Calcite crystals may indicate that the initial
firing temperature of all the samples from the two sites did not
exceed 800 oC. In addition, in all the samples, Quartz and Chert
were crushed before being intentionally added to the clay used for
the pottery production. For the purpose of increasing the clay
plasticity and decreasing the shrinkage upon drying, bone fragments (Fluorapatite) were added. Some samples from Tell Abu
Al-Kharaz indicated that the source of raw materials used for
making pottery vessels came from the Upper Cretaceous deposits
based on the presence of Foraminifer microfossils, Planulina Nacatochensis. Furthermore, the occasional presence of basalt-forming
minerals such as Augite and Plagioclase in some samples from
Tell Abu Al-Kharaz indicates that basaltic grinding tools were possibly
utilised for preparing the raw materials of pottery vessels.
