Buto, a major site in the north-western Delta, is characterized by the presence of significant Graeco-Roman pottery workshops. Geophysical surveys and excavations in the past twenty years have brought to light a number of kilns using radiating firing through flue tiles to produce red-slipped fineware—tableware and flasks—succeeding to the Ptolemaic black-slipped pottery. We underline here the specificities and uniqueness of these production units, which use a firing technique well-known in the West and produce shapes inspired from the Mediterranean—especially italic—repertory (thin-walled style ceramics and terra sigillata) since the Augustean period. We attempt to present the modalities presiding over the mobility of techniques and repertory, summoning up other examples from Asia Minor and the Eastern Mediterranean.
