摘要
This paper presents an investigation of Eneolithic painted ceramic artefacts, belonging to the Cucuteni culture (phases A and B), focused on the raw materials used for manufacturing the ceramic bodies and the pigments used for the painted decorations. Detailed information on their elemental and molecular composition were obtained by combining Energy Dispersive X-Ray Fluorescence (EDXRF), Energy Dispersive X-ray analysis in the Scanning Electron Microscope (SEM-EDX), and Fourier Transform Infrared (FTIR) spectroscopy for the analysis of the bodies and painting materials used for manufacturing the Cucuteni artefacts. X-Ray Difflaction (XRD) was also used to characterize the ceramic bodies. %26lt;br%26gt;The Eneolithic ceramic shards were divided into three decorative groups (red, black, and black on red). The major, minor and trace elements found on the decorated surface and in the clay body were determined. The bodies were found to be mainly composed of quartz, K-feldspar, plagioclase, clinopyroxene, hematite, calcite, and micas. The most predominant chemical elements were determined, and a representative ratio (Fe/Mn) was calculated and compared for each samples group. The analysis of the samples revealed a higher content of Fe in the red paint in comparison with the other areas (black and not pigmented) and leads to the conclusion that iron-rich clay was used. The red pigment could be attributed to iron oxide in the form of hematite.
