My registration to a thesis based on work experience is the outcome and recognition of a ceramologist career in Egypt within the framework of the Institut français d’archéologie orientale du Caire (Ifao). A large number of archaeological operations throughout Egypt feed my research and they have logically led me to enlarge the issue of regional pottery groups, to compare and to monitor them and to follow their developments from the Neolithic Period to the Islamic Period. The first part of the synthesis provides an archaeological inventory of pottery production centres published in Egypt, from the Predynastic Period to the Modern Era. The second part is devoted to the Egyptian regional pottery groups. A linear and diachronic approach was chosen for the implementation of a general course of regional pottery groups in Egypt from the seventh millennium to the end of the Ottoman Period, attempting to dynamically outline the ruptures or continuities. To illustrate the richness and relevance of this perspective for the study of Egyptian potteries, we propose two case studies that are to the opposite of each other, at a chronological and geographical level as well as at a cultural level. Indeed, each refers to very different historical, cultural and technical issues. One concerns the funerary pottery dated of the end of the Old Kingdom in Bahariya; the other study focuses on Egyptian domestic pottery at the beginning of the Ptolemaic Period, dated around the third century BC.
