The fact that Greek Southern Italy produced its own red-figure pottery as early as the end of the 5th century BC was first established by Adolf Furtwaengler in 1893 (A.D. Trendall).
Archaeological proof that this pottery was actually being produced in South Italy first came in 1973 when a workshop and kilns with misfirings and broken wares was first excavated at Metaponto, proving that the Amykos Painter was located there rather than in Athens (A.D. Trendall, p. 17).
Apulian potters, having a taste for the frilly and elaborate, take traditional forms such as the Panathenaic amphora, the oinochoe, the lekythos, attenuate their forms, exaggerate their flares, add volute handles, molded gorgoneia, affectionately dubbed "macaroons", and end up with extremely elegant new varieties of pottery which still fit within the Hellenistic aesthetic, and end up becoming standard in the subsequent Graeco-Roman world.
Apulian artists use polychromatic, coiling tendrils and flower forms including roses, poppies, and whirling swirls to fill necks and other traditionally black areas of vases.
Italiote artists also created a technique called "sovradipinto," in which multiple layers of colored slips were used to add chiaroscuro (highlight and lowlight) for figures and decorations.
This is the application of red and white slips on top of the black gloss rather than leaving figures and designs in reserve, as was the usual Athenian custom.
