Technological features of Apulian red figured pottery

Abstract

Apulian red figured pottery samples, dating back to the 5th and 4th centuries BC, from the archaeological site of Monte Sannace (Gioia del Colle, Bari, Italy) have been characterized from the physical–chemical, mineralogical and morphological points of view. Scanning electron microscopy, X-ray diffraction and atomic spectroscopy investigations have been carried out on the ceramic body, red decorated area and black gloss of the fragments, with the aim of outlining the technological features and of defining the nature of coatings and decorations. All 5th century fragments show the same features: fine texture of the ceramic body, red figures saved from the ceramic paste and black gloss painted directly on the ceramic body. The statistical treatment of compositional data of ceramic bodies excludes the local production of these objects. As regards the 4th century fragments, some show similar features to the 5th century ones; however others are characterized by the coarse texture of their ceramic body and an intermediate red layer of finer clay between the black gloss and the ceramic body. The analytical results make it possible to distinguish two different production technologies of red figured Apulian vases in Monte Sannace during the 4th century BC. Certain vases were produced using the “classic” Attic technology and others with a different technique, not previously known, which involved the application of a red engobe layer on the clay paste, before the black gloss painting.
