Area of Science:

  • Art conservation science
  • Materials science
  • Organic chemistry

Background:

  • Tempera painting, a historical art technique, predominantly used egg yolk as a binder.
  • Understanding the aging process of tempera paint is crucial for art conservation.

Purpose of the Study:

  • To simulate and analyze the aging process of egg yolk tempera paint.
  • To investigate the chemical transformations of egg yolk binder under light exposure.
  • To compare the aging patterns of pigmented and unpigmented tempera paints.

Main Methods:

  • Mockup tempera paints with specific pigments (lead tin yellow, azurite, Sienna) were artificially aged using visible or UVA light for up to 130 days.
  • Fourier-transform infrared (FTIR) spectroscopy was used to monitor chemical transformations in the egg yolk binder.
  • Thermal analysis was employed to assess degradation characteristics.

Main Results:

  • Egg yolk lipids and proteins undergo oxidation, evidenced by changes in FTIR absorption bands (e.g., CH2 and Amide I).
  • Pigments accelerated the chemical changes in the tempera binder compared to unpigmented samples.
  • FTIR analysis indicated conformational changes in proteins, and thermal analysis suggested lipid chain shortening during aging.

Conclusions:

  • The study elucidates the complex chemical evolution of egg yolk tempera binders over time.
  • The findings provide valuable insights into the degradation mechanisms of historical tempera paintings.
  • Understanding these processes aids in developing effective conservation strategies for aged artworks.
