An archaeometric application to a group of early Ottoman ceramics from İznik

Kırmızı, Burcu
This study investigates the physical, mineralogical and chemical characteristics of a group of pottery sherds that are mostly Miletus-ware ceramics, belonging to the Early Ottoman period and excavated during 2003 season, from the The sherds examined are mostly characterized by cobalt-blue designs which are occasionally coupled with black, green and purple paintings. After grouping the sherds according to their stylistic and color differences; petrographic, X-ray diffraction, scanning electron microscope coupled with energy dispersive X-ray and Fourier Transform Infrared analyses were carried out for investigating the mineralogical and chemical properties. Most of the ceramic samples have slip and glaze on both sides. The glaze part is mostly fresh without any devitrification products. Bodies of the ceramics have tones of reddish yellow and/or red, indicating abundant amount of iron in their raw material. Grains consist mainly of metamorphic rock fragments (quartz-mica schist), quartz, feldspar, hornblende, hematite and biotite. Pyroxene, epidote, chert, muscovite, opaque minerals, chlorite are also encountered. Micritic calcite occurs in some of the pores. Ceramic bodies investigated are usually fine-grained and well-sorted. Clay raw material used for the production of the ceramics seems to be originated from a metamorphic source. Bodies usually show a low degree of vitrification with few exceptions, indicating a rather simple technology with non-uniform and low degree of firing, probably not exceeding 900°C. Technological characteristics of the sherds examined do not seem to have changed much between 14th and 16th century.


An investigation on the mineralogical, petrogaphical and chemical properties of stone objects from Karain Cave, Antalya-Turkey
Efe, Mehmet; Günal Türkmenoğlu, Asuman; Kartal, Metin; Department of Archaeometry (2012)
The archaeological and technical questions about ancient stone tools lead to various research activities such as chemical and petrographical analysis. Considering research areas and publications it can be suggested that mineralogical studies of stone samples of ancient stone tools have disclosed useful information concerning identification of the stone. Within this context, aim of this study is to determine the chemical, mineralogical and petrographical identities of the stone samples of Karain Cave (Antaly...
Synthesis and characterization of clinoptilolite
Güvenir, Özge; Çulfaz, Ali; Department of Chemical Engineering (2005)
Clinoptilolite is the most abundant zeolite mineral in nature. In this study a reproducible synthesis recipe for clinoptilolite was established and the limits of the crystallization field were developed by changing synthesis parameters such as temperature, composition and the nature of reactants. Clinoptilolite was reproducibly synthesized as a pure phase and in high yield at 140oC using a benchmark batch composition of 2.1 Na2O:Al2O3:10SiO2:110.1 H2O. Clinoptilolite was crystallized from 10wt% or 28wt% see...
An archaeometrical investigation on provenance and technological properties of Seljuk period pottery from Komana (Tokat)
Er, Mehmet Bilgi; Ertaş, Gülay; Department of Archaeometry (2020)
The archaeological excavation at Komana (Tokat) unearthed great number of pottery reflecting wide variety in decorations and archaeological evidences including biscuit-fired pottery and tripod stilts showing local production of glazed pottery dated back to Seljuk period (12 – early 14th centuries). In this study, analytical techniques were used to identify the local compositional groups and import wares in the pottery collection, the production technology of local pottery, and to locate the clay used for th...
Material characterization of the late 12th-13th century Byzantine ceramics from Kuşadası Kadıkalesi/Anaia
Kırmızı, Burcu; Göktürk, Emine Hale; Günal Türkmenoğlu, Asuman; Department of Archaeometry (2012)
This study investigates the petrographical and chemical characteristics of a group of Zeuxippus Ware Related Ceramics dating to the late 12th-13th centuries from Kuşadası Kadıkalesi/Anaia. Kadıkalesi was a Byzantine fortress at the coast of Aegean Sea. It was also a significant commercial port and an episcopacy center during the 13th century. In this study, visual classifications of the ceramics were carried out based on their stylistic properties. Then, ceramic samples were investigated by several methods ...
The anatomy of a gabbro body and its bearings on the origin of mafic enclaves in the Ağaçören granitoid central Turkey
Güleç, Nilgün Türkan; Yusuf Kagan, Kadıoglu; Barbara, Barreıro (1996-01-01)
The origin of mafic enclaves and mafic magmatic rocks associated with the Cretaceous Aǧaçören granitoid (central Turkey) was investigated through field, petrographic, and geochemical studies along a contact between enclave-bearing granite and a gabbro body exposed at the top of the granite. Three zones were distinguished within the gabbro, from center to margin: massive gabbro, transitional gabbro, and shattered gabbro. Petrographic features display a continuous change from massive to shattered gabbro, repr...
