United StatesA new study published in the journal Nature Communications reveals that renowned Renaissance painters like Leonardo da Vinci may have intentionally used egg yolk in their oil paintings. Researchers analyzed trace protein residues previously thought to be contaminants and found evidence suggesting that the addition of egg yolk significantly altered the properties of oil paint, offering benefits such as improved resistance to oxidation and humidity. The study highlights the advanced technical knowledge of the 'Old Masters' and suggests that the practice of mixing egg yolk with oil-based paints originated in Central Asia before spreading to Northern Europe and Italy. By recreating historical paint-making techniques, scientists demonstrated how egg yolk could enhance the durability and performance of oil paints.
