Hypothesis

What materials and techniques did David Alfaro Siqueiros use in his mural painting?

Conclusion

The study revealed that Siqueiros used multiple binders, including nitrocellulose and PVAc, in his mural painting techniques.

Supporting Evidence

  • Siqueiros used multiple binders in successive layers in no apparent order.
  • Unexpectedly, polyvinyl acetate and different nitrocellulose monomers were identified.
  • The study confirmed an efficient methodology for studying very small and complex samples.
  • Findings provide valuable insights into Siqueiros' artistic techniques.

Takeaway

Researchers looked at tiny pieces of a mural by Siqueiros to find out what materials he used, and they discovered he mixed different types of paint.

Methodology

The study used optical microscopy, SEM-EDS, ATR-FTIR, micro-FTIR, and NMR spectroscopy to analyze the microsamples.

Limitations

The analysis was limited by the small size of the samples and the complexity of the materials.
