Abstract
We report a preliminary characterization of a blue pigment because its color has been associated to objects found from Aztec and Precolumbian times. The pigment was examined before and after its purification by a variety of techniques: Particle Induced X-ray emission (PIXE), electron paramagnetic resonance (EPR), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy coupled to energy dispersion spectroscopy (SEM-EDS). The relationship of the chemical composition, the spectroscopic signals and the color are discussed.
