Abstract. This research paper is devoted to identifying the glazed Achaemenid bricks in Persepolis. So far,
some studies have been carried out on the introduction on these bricks, but technical studies have not been
conducted. The glazed bricks reviewed in this paper are white, light green, dark green, dark brown, grey and yellow, and each color is surrounded by azure blue lines and separated from each other. Using X.R.D, S.E.M, D.T.A, T.G.A methods and more chemically, the bodies and glazes are identified, the body of this type of bricks is a very porous silica body. The light green, dark green and yellow glazes are made of lead. In the combination of all glazes, there are iron and magnesium, which probably existed in the original composition (base glaze), besides the color effects of impurities. After the extraction of the results of each test separately, the results were compared and the purpose of these tests was to recognize the glazes applied in these pottery bricks and this research is the result of laboratory studies of the authors.
Key word: Persepolis, clay bricks, wet chemistry method, Yellow glaze, Green glaze, Lead glaze.
