Challenges of analytical methods for the characterization of microsamples from David Alfaro Siqueiros mural painting.

ABSTRACT: This study presents the analysis of seven microsamples from Untitled Mural 3, painted by David Alfaro Siqueiros between 1964 and 1972. The mural has never been restored, therefore preserving the materials used by the artist. The microsamples were analyzed using a combination of techniques: optical microscopy (OM), scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS), attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), micro-Fourier transform infrared spectroscopy (micro-FTIR) with reflection mode, and high-resolution nuclear magnetic resonance (NMR) spectroscopy. In this work, compounds common to those identified in the analysis of the contemporary mural Trazos de composición piramidal composition were identified, such as acrylic and nitroc
