Özet:

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.
