Each year almost 150.000 tons of boron containg clay wastes are produced in Etibor Kirka Borax Company's Derivations Plant. It would be very advantageous if these wastes could be used as main ceramic raw material considering the depletion of clay and other ceramic raw materials. In this study, some physical and mechanical properties of wall tiles produced by the addition of DSM clay wastes to silica sand were investigated. From the results, it is possible to say tiiat boron bearing DSM clay wastes could be used with silica sand as a filler in wall tile body.

Lead glazed pottery shows the main characteristic of the medieval age Anatolian ceramics [1]. In this study lead glazed pottery belongs to 14 th 15 th centuries excavated from Ayasuluk Ephesus was investigated to enlighten the composition of the body, glaze and the crystals formed in the interaction zone. For this purpose, cross-sectional samples were prepared by cutting and polishing down to micron surface finish. Then, the microstructural and chemical analysis were performed by using scanning electron microscope (SEM-Zeiss Supra 50 VP) attached with an energy dispersive x-ray spectrometer (EDX-Oxford Instruments) and transmission electron microscope (TEM-JEOL 2100 F) attached with an energy filter (GATAN GIF TRIDEM), electron energy loss spectrometer (EELS), a high angle annular dark field scanning transmission electron microscope (STEM–HAADF) detector and an EDX (JEOL JED-2300T) spectrometer. For the TEM investigations, the crystals were prepared by using focussed ion beam (FIB) ...

ABSTRACT The region covering Southeastern Anatolia takes place in upper Mesopotamia, so it has numerous cultural heritages due to its witness to various social movements of different civilizations in ancient times. Kuruki Mound is located on the junction point of Tigris River and Batman Creek, near Oymatas village which is almost 15 km to Batman, Turkey. The mound is dated back to Late Chalcolithic. Archaeological excavations are carried out on two hills named as “Kuriki Mound-1” and “Kuriki Mound-2” in which 4-layer and 2-layer settlements have been revealed, respectively. This region will be left under the water by the reservoir lake of Ilısu Dam when its construction is completed. Thus, characterization of ancient materials such as potsherds, metals and skeleton ruins should be rapidly done. In this study, 12 potsherds excavated from Layer-1 (the first settlement layer after the surface) in Kuriki Mound-2 were investigated by FT-IR spectrometry. Energy dispersive X-ray fluorescence (EDXRF) and X-ray diffraction (XRD) analyses were used as complementary techniques in order to expose chemical and mineralogical/phase contents, respectively. Obtained results showed that the potteries have been produced with calcareous clays and they include moderate amounts of MgO, K2O, Na2O and Fe2O3 in this context. Additionally, high temperature phases have also been detected with XRD analyses in some samples.
