  Rezumat:   The paper presents the results of the mineralogical and physical investigation performed on 10 fragments of Roman ceramics (oil lamps, bowls, plates) out of the 20 samples collected from the west-east Section of the Basilica extra muros Sector, Histria (Constanţa County, Romania). Our goal was to define the physiographical features: structure, texture and firing parameters for this group of ceramic objects. The original 20 archaeological objects are represented by oil lamps (4), plates (8), bowls (6), one jug, and one terracotta – all in the form of fragments. From the technical realisation point of view, 13 objects were pressed in moulds, while the rest (7) were formed on the potter’s wheel. Excepting three objects that lack decoration, the rest show various decorations: in relief, incised or printed. The 10 ceramic fragments we have investigated are representative for the original group of 20 samples. They were investigated macroscopically, microscopically, by X-ray diffraction (XRD), and for their compaction characteristics: water adsorption, density and apparent density.Based on their macroscopic and physical features, as well as on the mineral composition by XRD, we could separate two categories of ceramics fired at different temperature ranges: (1) 800°-900°C (6 samples), and (2) 900°-950°C (4 samples).
