"Tol-e- Ajori" is one of the most important ancient sites that is located in Marvdasht plain and three seasons of excavations have been carried out on this site. The goal of expeditions in the excavation of Tol-e- Ajori is the discovery of architectural remains from Achaemenian period which is also decorated with glazed brick.
These investigations focused on the characterization and manufacturing process of glazed bricks. Archaeometrical studies are dedicated to technology of the bricks and the glaze through the laboratory studies. Analytical strategies carried out by means of using XRD & XRF, thermal analysis (DTA & TG), and petrographic studies in order to get related information about technology and the manufacturing process of the bricks. Quartz identified as the main phase constituting the bricks in a brick texture fine and uniform dispersion, and formation of secondary phases such as calcite, sericite, anorthite, gehlenite and pyroxene in the brick’s texture suggests that the temperature is approximately about 1100 to 1140°C. Recrystallization of secondary phases were also be the major distraction effect in the body of the Bricks The complex of lead antimony and lead bismuth were the main base of chemical composition of the glaze.
