    Investigations of Black and Red Figure Pottery Shards and Local Clay, Excavated at Ainos (Enez-Turkey), by Multiple Analytical Techniques
    (Elsevier, 2023) AKYÜZ, SEVİM; Çelik, Sefa; Kurap, Gülnur; Özel, Ayşen E.; Başaran, Sait
    Mineralogical compositions as well as firing conditions of black and red figure pottery shards, belonging to 4th6th century BC, excavated at the archeological site Ainos (Enez-Turkey), were investigated using Fourier Transform Infrared (FT-IR), micro-Raman, and X-Ray Powder Diffraction (XRPD) techniques. Raw clay, obtained from a clay bed, that was unearthed during the archeological excavations at the same site, was also analyzed for comparison. To determine the firing temperature of the pottery shards, ceramic tablets were prepared from this raw clay sample (in three different firing temperatures: 650, 700 and 900 degrees C) and analyzed. The results allowed us to identify the mineral composition and to discuss the firing conditions. Chemometric analysis on the IR data was performed for revealing the distinct groups.

    Investigations of Archaeological Glass Bracelets and Perfume Bottles Excavated in Ancient Ainos (Enez) by Multiple Analytical Techniques
    (Springer, 233 Spring St, New York, Ny 10013 USA, 2018-03) Özel, Ayşen E.; Kecel Gündüz, Serda; Başaran, Sait; AKYÜZ, SEVİM; AKYÜZ, ZEKİ TANIL; 10127; 110745; 110526
    Fragments of two perfume bottles belonging to the Hellenistic and Roman periods, and five bracelets belonging to the Roman, Byzantine, and Ottoman periods, excavated in the archaeological site of Enez during the excavations in 2000, have been investigated. The samples were analyzed using micro-Raman, FTIR, and energy dispersive X-ray fluorescence techniques, in order to study the ancient technology of glass production and to determine chemical compositions of the basic components and coloring elements of the glassware. All the investigated glasses can be characterized as low-magnesia-soda-lime silicate glasses, whose colors are induced by metal ions. The melting points of the investigated glasses are estimated to be quite close to each other and around 1000A degrees C.

    FTIR Spectroscopic and Chemometric Investigations of Ancient Potteries, belonging to 4th-6th Century BC, excavated in Ancient Ainos (Enez)-Turkey
    (2018) Başaran, Sait; AKYÜZ, SEVİM; 10127
    Ancient potteries are important source of materials on many aspects of the past such as civilization, trade and technology. Potteries are made of clayminerals and the common major clays used in making potteries are in smectite or kaolinite group of clay minerals. Clay minerals as the main material for the production of potteries show some characteristic reactions during the firing; e.g. dehydroxylation, decomposition and phase transformation. Thus, the firing conditions can be estimated by the absence or occurrence of the specific mineral assembly. IR spectroscopy, in conjuction with x-ray diffraction, is a powerful tool for clay mineral analysis, thus for the mineralogical characterization of potteries. Using the infrared spectra, unique information about the group of minerals in which the specimen belongs, the degree of crystalline and non-crystalline impurities can be determines and reactions of minerals with chemicals in their environment can also inferred. Recently the IR spectroscopic data is used together with statistical analysis methods such as Principal Component Analysis (PCA) and Cluster Analysis for grouping / provenance studies of potteries. in this study a set of twenty pottery fragments, coming from archaeological excavation in EnezTurkey, was investigated by FT-IR and Chemometric techniques, XRD was used as complimentary technique. FT-IR data provided a detailed description of the minerals contained in the pottery findings, whereas the chemometric analyses were found to helpful to find the similarities between the samples, which gaye meaningful interpretation to archeological studies. The whole set of samples shows a general similarity in the mineralogical composition, compatible with the geological conformation of Enez. Enez area is famous by clay deposits. The illite and montmorillonite were the main clays of this area. Calcite concentration was found to different in all samples but presence of also microcline indicated that CO3is primary and comes as impurity of the local clays. Feldspar phases were inferred from the second derivative profiles of the IR spectra. The absence of any firing mineral in the ceramic body is a clear indication of low firing temperature. Dark brown and black coloration was due to different concentrations of Mn02, magnetite and red coloration was due to hematite. Spectroscopic results indicated that the potteries were fired to a temperature less than 8000C in the oxid izi ng atmosphere.

    (Asian Journal Of Chemistry, 11/100 Rajendra Nagar, Sector 3,, Sahibabad 201 005, Ghaziabad, India, 2013-12) Başaran, Sait; Çakan, Banu; AKYÜZ, SEVİM; AKYÜZ, ZEKİ TANIL; 10127; 111424; 53588
    Ancient glass fragments excavated in the archaeological district Enez (Ancient Ainos), Turkey were investigated by combined energy dispersive X-ray fluorescence (EDXRF) and Fourier Transform Infrared (FTIR) spectrometry techniques. Multi-elemental contents of a spirally twisted translucent yellow glass bracelet, fragment of a turquoise blue vessel and its cover and a fragment of a translucent white vase decorated with a surface coating, that belong to Ottoman period were determined by EDXRF method. The concentrations of 23 elements (Na, Mg, Al, Si, S, K, Ca, Ti, Cr, Mn, Fe, Co, Cu, Zn, As, Br, Rb, Sr, Sb, Ba, Ce, U, Pb) which might be present in the samples as flux, stabilizers, colorants or opacifiers and impurities, were examined. The glasses were classified as potassium-limy glass. IR reflection and absorption spectroscopy enable us to determine structural characteristics of the glasses.
