Reconstructing the history of archeological artifacts leads us to examine the materials using various scientific methods. Therefore, archaeometric investigations allow us to understand the production technology, the firing temperature, provenance, the raw materials and the colorants used in the process. This thesis aims to investigate the archaeological glasses found at the Side excavation site. Visual and optical microscope analyses were conducted to observe the physical shape, deterioration types, and the production technology of Side glass. According to the thickness measurements and their bubble shapes, Side glasses from the Late Antique period were shaped by the glass blowing technique. The color analysis has revealed that the Side glasses in various color ranges were mainly in green and blue hues. The chemical analysis of the Side glasses was conducted by Polarized Energy Dispersive- X-ray Fluorescence (PED-XRF). The results of the analysis were interpreted with respect to main, minor and trace elements. In line with these results, Side glass set was a soda-lime-silica glass fluxed with natron. The vast majority of the glasses were decolorized by the deliberate addition of manganese. The colorants are iron, copper, cobalt, manganese, vanadium, and lead. Recycling conditions were revealed using the marker elements and a comparative plot of Side and primary production glasses. In accordance with the glass composition, glass groups were identified by hierarchical clustering and were compared with Late Antique glass from Asia Minor. Furthermore, clay-based crucibles and kiln fragments were analyzed by the thin section optical microscopy. Petrographical properties of the crucibles were demonstrated in terms of rock and mineral contents, the exposed firing temperature and their origins.

Archaeometric analysis on the selected samples of glass artifacts recovered in the excavation of Alanya castle / Aksoy, Uğur Bülent; Demirci, Şahinde; Department of Archaeometry (2006) The archaeological and technical questions about ancient glass have lead to various research activities such as identification and sourcing raw materials used in the glass production, investigation of the ways in which colors can be modified according to furnace atmosphere and times of firing. Considering research areas and publications it can be suggested that compositional studies of well-dated samples of ancient glass have disclosed useful information concerning raw materials characteristics and producti...
Archaeometrical investigation of some medieval glass samples from Alanya region Beşer, Elif; Uzun, Ali; Department of Archaeometry (2009) The archaeological questions of historical glass have lead to remarkable research activities such as identification and sourcing the raw materials used in the glass production, investigations of the ways in which the colors of glass can be modified due to dissolved and/or colloidal coloring agents, the furnace conditions, and the time of fritting and melting. Considering publications, it can be suggested that compositional studies of well-dated glass samples have supplied useful information concerning raw m...
Improved methodology for identification of Goktepe white marble and the understanding of its use: A comparison with Carrara marble Wielgosz-Rondolino, Dagmara; Antonelli, Fabrizio; Bojanowski, Maciej J.; Gladki, Marcin; Göncüoğlu, Mehmet Cemal; Lazzarini, Lorenzo (2020-01-01) The provenance of marbles used for ancient statuary and architecture is of utmost importance for archaeologists, art historians and archaeometrists. The aim of this paper is to provide a comprehensive characterisation of the white marble exploited in antiquity in Goktepe (Mugla Province, Turkey) to increase the reliability for identifying this marble in ancient artefacts. A campaign of interdisciplinary archaeological and geological fieldwork undertaken by the Marmora Asiatica project is based on a multi-me...
Biological decay and its control by biomineralisation in calcareous stones Üstünkaya, Meltem Cemre; Saltık, Emine Nevin; Department of Archaeometry (2008) Biodeterioration has an important role in weathering of historical materials. Natural stone materials become vulnerable to physical and chemical changes in outdoor conditions, favouring the biological growth. In this study, biodeterioration on calcareous stones and its control by biomineralisation were studied on limestones from Nemrut Mount Monument and marbles from Pessinous Archaeological Site. For qualitative and quantitative detection of biological activity fluorescein diacetate (FDA) method that was d...
"The citadel of Ankara": Aspects of visual documentation and analysis regarding material use Sülüner, Hasan Sinan; Bakırer, Ömür; Department of Architecture (2005) This thesis examines the history, written sources and physical aspects of the citadel at Ankara with respect to building materials, masonry styles, design and topography. The distribution of different types of building materials in selected areas are analyzed and documented by using modern methods.
