LOPEZ MILLA, Alcides  and  OLIVERA DE LESCANO, Paula. Caracterización de pigmentos aplicados en material arqueológico de la Cultura Chincha por fluorescencia de Rayos X y microscopía electrónica de transmisión. Rev. Soc. Quím. Perú [online]. 2007, vol.73, n.1, pp.03-17. ISSN 1810-634X.

The elementary characterization of some pigments applied in the decoration of recipients used by our ancestors of the Chincha Culture by Energy dispersive X-ray fluorescence (EDXRF) method was allowed. Additionally, the morphological and crystalline characterization by Transmission Electronic Microscopy (TEM) method has been possible. The results have allowed identifying the presence of mercury sulphur (HgS) (cinnabar) in the red pigment on the "mate"; the black and white pigments are constituted by materials of organic aspect; in the case the dark brown one they are constituted by organic matter and ferric oxide. This work also demonstrates that a portable EDXRF spectrometer is the most suitable for the study of pieces of our cultural patrimony, mainly of those that are difficult to transport from an archaeological place or museum to an analytic laboratory by reason of its dimensions and conservation conditions.

Keywords : Pigments; archaeological material; Chincha Culture; XRF; TEM.
