Scientists Uncover Egg Yolk's Role in Da Vinci's Masterpieces

Germany - Ekhbary News Agency

A recent study published in Nature Communications suggests that renowned Old Masters, including Leonardo da Vinci, Sandro Botticelli, and Rembrandt, intentionally used proteins like egg yolk in their oil paintings. Previously, protein traces were often dismissed as contamination, but new research indicates a deliberate artistic choice. This discovery sheds light on the sophisticated technical knowledge of 16th to 18th-century European painters and their innovative paint preparation methods.

According to Ophélie Ranquet, a study author from the Karlsruhe Institute of Technology, even minimal amounts of egg yolk dramatically improved oil paint properties. It enhanced durability by slowing oxidation due to antioxidants and made pigments like lead white more resistant to humidity, simplifying application. Furthermore, egg yolk allowed artists to create stiffer, impasto textures with less pigment, a crucial advantage when precious materials like lapis lazuli were more expensive than gold. This innovative use of a common ingredient profoundly influenced the longevity and aesthetic qualities of iconic artworks, such as Da Vinci's "Madonna of the Carnation," which exhibits unique aging characteristics potentially linked to these techniques.
