Manufacture technology involves several aspects of potterymaking, such as the type and the atmosphere of firingto obtain the finished item. During the firing of clay, at different environment of the oven, different compounds ofiron (Fe(II) and Fe(III)) are formed and this is the reason for a different color of the ceramic body. Despite the greatinterest in this field, no works are devoted to the study the speciation of iron in ancient ceramics.The proposed method, even if considered destructive by archaeologists, allows the speciation of iron, usingquantity of sample in the order of milligram. In order to achieve information about their firing conditions, thirtyninepottery samples belonging to the archaeological Sicilian site of Himera (Sicily, Italy) were characterized forFe(II) and Fe(III) by means of a UV–Vis spectrophotometricmethod proposed by us,while total iron was checkedby ICP-OES. Were identified two groups of samples, the first (A), which is particularly rich in Fe(II) (thearchaeologists have not identified the stylistic characteristics ofmost of this samples) the last group is instead richFe(III).
