Özet:

Olba archaeological site is located in Mersin, Turkey. It is one of the most important regions of Rough Cilicia. We performed the analyses of 34 glass objects (IV. and VII. centuries C.E.) from Olba archaeological site using PED-XRF and Raman spectroscopy techniques. XRF and Raman spectroscopy results are mostly compatible with each other. The chemical compositions of the Olba glass samples are similar to each other and the results showed that the glasses are all soda-lime-silica based glasses. Additionally, for the production of the Olba glasses, soda was used as the fluxing agent and the main stabilizer was lime. SiO2, Al2O3 and Na2O levels of Olba glass samples are relatively lower than typical soda-lime-silica glasses reported in the literature. Raman analyses results revealed that the Olba glasses were fired at temperatures above 1000°C according to their Ip values found to be higher than 1.
