This work evaluates the chemical composition of pigments used in decorative paintings in the coffin cartonage fragments and linen wrappings of an Egyptian mummy, using X-ray microfluorescence with synchrotron radiation technique. The measures were obtained at the XRF beamline of the National Synchrotron Radiation Laboratory (LNLS). This Roman period female mummy is one of the most important mummies in the National Museum because of its unconventional embalming with disarticulated legs and arms. X-ray fluorescence analysis is a widely used spectroscopic technique in archaeometry for investigating the chemical composition of pigments in manuscripts, paintings, ceramics and other artifacts, metal alloys, and stones. Knowledge of composition allows pigment characterization through major or minor constituents, and makes it possible to establish the provenance, age, and consequently, the authenticity of the artifact.
