Caracterización fisico-química de los morteros y de las pinturas murales de la villa romana de El Ruedo (Almedinilla, Córdoba)

Abstract

In the present survey, we have proceeded to the analysis of Roman mortars and paintings in two rooms from a villa at El Ruedo (Almedinilla, Cordoba). They were used different techniques or procedures, such as: analysis granules size, X ray diffraction and scattering reflection. It has been noticed that materials of the different decorations correspond to different compositions provenient from different sites (different canters). As far as colours are concerned, they were established the different parameters which define them in every international system. The scattering reflection techniques allowed us to identify the pigments, emphasizing that their mixtures are usually based upon only in one colour, lighter or darker.
