XRF mapping of painting reconstruction, inspired by Johannes Vermeer's "Girl with a Pearl Earring"

<p>This dataset contains the XRF mapping of painting reconstruction, inspired by Johannes Vermeer&rsquo;s &ldquo;Girl with a Pearl Earring&rdquo; produced in the Microchemistry and Microscopy Art Diagnostic Laboratory (M2ADL) of the University of Bologna (2018). The painting was obtained by applying pigments mixed with linseed oil on a commercial canvas. Pigments were selected considering their elemental signals detectable by XRF spectroscopy. In a more detail, azurite (Cu₃(CO₃)₂(OH)₂) was used for the creation of the veil, lead white ((PbCO₃)₂&middot;Pb(OH)₂) for the flesh tone and vermilion (HgS) for the lips. The XRF map was collected with the micro-XRF portable spectrometer (<em>ELIO</em>) produced by BRUKER. The XRF system is equipped with a rhodium-target X-ray tube. The voltage range is between 10 and 50 kV, and the anode current range is between 5 and 200 &mu;A. The X-ray fluorescence is revealed by a Peltier-cooled silicon drift detector (SDD) with CUBE technology, with an active area of 50 mm². The typical energy resolution for Mn-K&alpha; radiation is &lt;140 eV. A motorized XY stage is mounted on a tripod for mapping analysis with a total travel of 100 mm x 100 mm. The collimator used for the analysis was of 0.5 mm.</p> <p>Please, cite as:</p> <p>R. Rocha de Oliveira, C. Malegori, G. Sciutto, P.
