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 production technology. Within this context, aim of this study was to determine the composition and technology of some 13th century Seljuk period window glasses from Alanya Castle archaeological site. During the excavations at the area called Vaulted Galleria in Alanya Castle many glass pieces in different sizes and colors had been found. In this study 10 samples were examined. Elemental analysis of the samples have been made using two different methods / X-Ray Fluorescence Spectroscopy (XRF) and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) to determine major, minor and some trace elements. The XRF and ICP-OES data reflect the typical composition of a soda-lime-silica glass with the average values of / 12.9% (Na2O): 7.7% (CaO): and 65.5% (SiO2). Samples were grouped by color as green, blue and purple. Color producing elements are Fe, Mn, Cu and Co. Most of the samples had shown casting character as production technique.

This dissertation examines five wooden hypostyle mosques built in Anatolia during the second half of the seventh/thirteenth century: the Sahip Ata Cami in Konya (656/1258) / the Ulu Camis of Afyon (671/1272) and Sivrihisar (673/1274-75) / the Ahi Serefettin Cami in Ankara (689/1289-90) / and the Esrefoglu Cami in Beysehir (696-698/1296-99). It aims primarily to explain how the condition of suzerainty prevailing after the Mongol Conquest in 641/1243 lead to the introduction of a new, wooden type of construction and caused it to proliferate. The dissertation employs a cultural-mode-of-production analysis to understand the circumstances of the type&rsquo / s introduction, with special emphasis on the place of wood in Islamic sacred building, the crisis of Islam after the Conquest, the cultural parameters of Seljuk patronage and the character of Mongol suzerainty.

The aim of the study was to investigate Seljuk Plasters used in some of their royal administrative or residential buildings from a viewpoint of their raw materials and technological characteristics. Some Byzantine Plasters of the same period were also investigated to make comparison. Plasters from some historic structures in the archaeological sites namely / Alanya Castle, Kubadabad Palaces, Syedra Archaeological Site, Aspendos Amphitheatre, Selinus Archaeological Site-Sekerhane K&ouml / sk and Hasbah&ccedil / e were examined. In a series of examination basic physical properties of the plasters as bulk density, porosity, water absorption capacity and water vapour permeability were obtained. The results indicated that plasters are low dense and high porous materials and having good breathing property. Mechanical properties of the plasters were expressed by the modulus of elasticity (Emod) values which were obtained from ultrasonic pulse velocity measurements. The Emod of the plasters being in the range of 1.0 to 5.6 Gpa show that they have enough mechanical strength comparable to historic mortars and bricks. Raw material composition and mineralogical properties of plasters were determined by combined interpretation of several types of analyses such as chemical analyses, particle size distribution of aggregates, petrographic analyses of thin sections by optical microscopy, scanning electron microscopic analyses of cross sections coupled with EDX for image analyses and semiquantitative elemental analyses, X-ray powder diffraction analyses for the determination of mineral phases, thermogravimetric analyses and FTIR analyses. Binder used in all plasters was found to be lime with amount in the range of 53.8-96.8% as CaCO3. The main minerals of aggregates are quartz, calcite (limestone), dolomite and opal-A. Regarding particle size distribution of aggregates it was possible to classify them into fine, coarse and mixed aggregates having rather high pozzolanicity. Study on decorative and red zigzag patterned plasters indicated presence of haematite as the source of red pigment. Study on green colored plaster also indicated presence of iron containing mineral with lower oxidation state. The Seljuk and Byzantine Masonries chosen are still surviving buildings that their plasters should be of good quality. In fact, this study approved their quality which may be due to the presence of opal-A and dolomite.

The aim of this study is to examine the technology of the relatively deteriorated historic tile, brick and mortar samples of Sivas G&ouml / k Medrese and Tokat G&ouml / k Medrese. Their main deterioration factors were analyzed mainly as salt weathering. It was examined in detail, and the possible desalination methods were discussed. For this purpose, the studies were carried out with a field survey and laboratory experiments on the two sites. Documentation of visual decay forms of Tokat G&ouml / k Medrese were done with AutoCAD. The density and porosities of tile body and mortar samples were determined by using RILEM standards. The pore size distributions of tile and mortar samples were examined by Mercury Intrusion Porosimetry. Modulus of elasticity of tile body and mortar samples was determined and compared with the other Seljuk building materials. Mineralogical compositions of the tile body and glaze, adhesive tile mortars of Sivas G&ouml / kmedrese and Tokat G&ouml / kmedrese were analyzed with X-Ray Powder Diffraction (XRD). Their microstructure and chemical compositions were determined by using Scanning Electron Microscope coupled with Energy Dispersive X-Ray Spectroscopy (SEM-EDX). The salts were determined for various methods such as spot tests and XRD analyses. The possible treatment methods of salt crystallization were discussed according to the properties of the examined samples. One of the most essential causes of decay factor was salt crystallization for the two buildings which causes detachment and loss of tiles. The deteriorations were distributed over the upper and lower sides of the wall which were close to the dampness zones from the roof and above ground. The experiments proved different kinds of salts such as thenardite, sylvite, halite, natrite, nitratine and niter coming from the ground and the restoration materials such as cement based mortars. The relative humidity of the environments was compared with that of salt characteristics. It was proved that the tiles were adversely affected from salt crystallization. The best desalination method was discussed. Advection method by using poultices was based on the transformation of ions through the flowing moisture. The most prominent characteristic of the poultices must have smaller pore size distribution than original salty materials. The pore size distributions of the tiles and gypsum mortars were determined to compare and chosen the best poultice from the literature. It was concluded that kaolin-sand-based poultices having known properties was the best one as considering the pore size distribution of the tiles and mortars. The study on material properties and desalination process was expected to help different monuments having salt problem.

The subject of this thesis is the restoration project of Zazadin Han, which is a 13th century Seljukid caravanserai near Konya. Following a brief description of the building, the values of the building and the aim of study are discussed in the introduction chapter. It is followed by the methodology of the study, detailed description of the building, analysis about the structural, material and construction features of the Han, historical study about the building type and the building itself, respectively. The restitution chapter is based on the information gathered in the previous parts. In the last chapter, a restoration project is proposed for Zazadin han.
