Jordi Ibañez Insa and Soledad Álvarez Pousa, members of the staff of the GEO3BCN-CSIC X-Ray Diffraction service (XRD), characterised the Salvador Dali’s jewel “The Angel Cross” by using X-Ray fluorescence spectrometry (XRF) in collaboration with Dalí Musem.
Ibáñez and Álvarez conducted the analysis in the Dalí Museum facilities (Figueres) using the XRF handheld spectrometer. The tool, which was mounted on a tripod, allowed the researchers to measure several parts of the jewel including the shell, the Jesus Christ figure, the platinum spines, the lapis lazuli ball on the base, and one of the gems.
The analysis was aimed to determine the elemental composition of the different parts of the jewel, which was designed by Salvador Dalí in 1960. “The angel cross” is part of the jewels collection of the Gala-Salvador Dalí Foundation.
The XRF handheld spectrometer allows the members of the XRD service to collaborate often with several museums in the characterization of art pieces. XRD service has collaborated in recent years with the Picasso Museum, the Museu Nacional d’Art de Catalunya (MNAC) or the Royal Monastery of Santa María de Pedrables.
