This study investigates the petrographical and chemical characteristics of a group of Zeuxippus Ware Related Ceramics dating to the late 12th-13th centuries from Kuşadası Kadıkalesi/Anaia. Kadıkalesi was a Byzantine fortress at the coast of Aegean Sea. It was also a significant commercial port and an episcopacy center during the 13th century. In this study, visual classifications of the ceramics were carried out based on their stylistic properties. Then, ceramic samples were investigated by several methods including mineralogical, micromorphological, chemical (SEM-EDX, ICP-OES, ICP-MS) and Raman Spectrometry techniques and further evaluated by statistical analyses. Bodies are found to be rich in SiO2 and Al2O3 while relatively high amounts of Fe2O3 measured, agree well with their reddish bodies. These bodies mostly display micaceous matrix with a relatively low degree of vitrification. Cluster analysis performed among thirty selected samples, points out the presence of two main groups. Observed slip layers are also found to be rich in SiO2 and Al2O3 contents and exhibit various types of crystalline and/or vitreous matrix. Glazes are found to be high lead glazes processed at or below. The glazes are found to be high lead glazes processed at or below 700°C as confirmed by SEM-EDX and Raman spectrometry investigations. Iron compounds are the major coloring agents for most of the glazes analyzed regardless of their observed colors. Presence of Raman peaks in some yellow glazes which may be assigned to a solid solution of Naples yellow type of pigment is significant since its use in the Byzantine period as a glaze pigment has been scarcely reported before.
