Resumen
En este trabajo, se ha utilizado la microscopia Raman para hacer un estudio de la composición química de los pigmentos empleados en la decoración de un conjunto de muestras de pinturas murales. Los muestras en cuestión, cuya datación se estima entre los siglos I y II d.C., fueron recuperadas del llamado Edificio D del Conjunto Arqueológico de Cástulo, ciudad ibero-romana situada a unos 6km de la localidad de Linares (Jaén). Se han analizado cuatro muestras, procedentes de las estancias 1,6, 7 y 9, en ellas se muestra la paleta de colores típicamente empleada en la elaboración de pinturas murales de origen romano, compuesta por blanco, rojo, amarillo, azul y verde. Finalmente, el empleo de dicha metodología ha permitido identificar las siguientes especies existentes en las muestras: hematites, óxidos de plomo, calcita, carbono amorfo, azul egipcio, tierras verdes, goethita y cinabrio
In this work, Raman microscopy has been used to make a study of the chemical composition of the pigments used in the decoration of a set of samples of wall paintings. The samples in question, whose dating is estimated between the 1st and 2nd centuries AD, were recovered from the Building D of the Archaeological Ensemble of Cástulo, Ibero-Roman city located about 6km from the town of Linares (Jaén). Four samples have been analyzed, coming from rooms 1,6, 7 and 9, in them the color palette typically used in the elaboration of Roman wall paintings is shown, consisting of white, red, yellow, blue and green. Finally, the use of this methodology has allowed the following species to be identified in the samples: hematite, lead oxides, calcite, amorphous carbon, Egyptian blue, green earth, goethite and cinnabar.
