Most ofthe historical paints are mainly constituted by inorganic pigments, either pure or mixed, spread onthe surfaces using different binding agents. The knowledge ofthe exact amount of different constituents ofthe paint, as well as ofthe mixing and pictorialtechniques, is crucial for a careful program of conservationof polychrome works. Moreover, since the availability of these pigments has been changing through thecenturies, their identification and chemical characterisation is useful to acquire or deepen informationaboutthe artist and his/her work. This information can also be useful for authentication purposes throughrelative dating because the identification of one pigment respect to another one can be used as a terminuspost quem or ante quem the artwork was realized. In this work, X-ray fluorescence data from historicalpigments, both pure and mixed, will be presented, in order to obtain quantitative information on thesamples and to extract calibration curves to the aim of evaluating the pigment concentration in unknownmixtures.
