- Abstract
The first use of window glass in buildings can only be found in the 1st century AD during the Roman period. It is known that window glass was mostly used in the caldariums, which are the warm rooms of the baths, and in the residences of the period during the Roman Imperial Period. In this study, window glass samples from the Late Roman period, obtained from the Metropolis Lower Bath-Palaestra and balneum excavations, were examined archeometrically. The samples were cataloged, photographed and documented. Their physical properties and production technologies were tried to be determined by microscopic studies. The chemical structure of the glasses was determined by PED-XRF analysis. As a result of the analysis, it was understood that the glasses were of the soda/lime glass type, which constitutes the most examples of the period. The high SiO2 contents of the samples indicate that both the mechanical resistance and durability and the melting temperature of the glasses are high. While the window panes of the Lower Bath-Palaestra were cylindrical blown, those found in balneum were produced by casting technique. It was understood that plant ash was added to the glasses with its high K2O content. Colorants in glass samples are Fe, Mn, Cu and Pb. In addition, it was observed that Sb was added to the structure of most of the samples as a decolorizer. The similarity of Al2O3 and/or SiO2 ratios, one of the main raw materials of glass, indicates that the raw materials comes from the same source(s). In the light of the Sr and Zr contents of the samples, it is possible to say that mostly marine origin sand source was used in the production of all the glasses of the sample set.
