A group of the late 12th-13th century Byzantine pottery glazes, mostly related to Zeuxippus Ware Type pottery from the Kuadas Kadkalesi/Anaia site in western Anatolia, was characterized non-destructively using Raman spectrometry. SEM-EDX was also used complementarily for the glaze characterization. The nature and composition of the glazes, firing conditions, aspects of colour formation and pigments used were discussed. The glazes were found to be lead-rich silicates, fired close to 700 degrees C on the basis of the Si-O stretching peak maxima of the Raman spectra recorded at approximate to 920-980cm(-1), as also confirmed by SEM-EDX analysis. The polymerization index values calculated are between approximately 0.05 and 0.1. The use of biscuit-fired bodies prior to glaze application was suggested based on the results of SEM-EDX analysis. In particular, the detection of Naples yellow pigment variations on a locally produced pottery sample is quite significant, since the use of this type of pigment has hardly ever been reported between the Roman period and the Renaissance.
