Abstract:

In this study, 7 archaeological ceramic samples taken from the Yenikapı rescue excavations in the Marmaray metro station-ion construction area carried out by the Istanbul Archaeological Museums were addressed. ATR-FTIR spectroscopy technique has been applied to determine the freezing temperatures and conditions of ceramic samples on the settlements that have been found from the Neolithic Period to the Byzantine and Turkish Period. The ATR-FTIR spectrum of the samples is taken in the range of 1800-400 cm-1 wave numbers. 2 degree by taking advantage of the derivative spectrum (2 to polinomal degree and 11. level Savitzky-Golay softing point) Mineral composition and baking temperatures of all ceramic samples belonging to Yenikapı have been successfully detected. According to the results obtained, it was observed that most of the ceramic samples studied were produced from a light-calculated symectistic flame and consisted mainly of meta-simectites, quarts, calcites and algae. It has also been detected in different proportions recarbonated-calsite, meta-caolinite, diop-sit, Al-OH, illite, MnO2, magnetite, anortite, ortoclass and hematite. Most of the ceramic samples studied due to the presence of detected metasimetite, Al-OH, anortite, ortoclass and hematite/magnetite minerals were found to be baked in a slightly elevating air between 600-800 oC.
