Old Masters Used Egg Yolk in Oil Paint, Study Reveals
In a groundbreaking study, researchers have uncovered that renowned artists such as Leonardo da Vinci and Sandro Botticelli likely incorporated egg yolk into their oil paintings. This finding reshapes our understanding of artistic techniques during the Renaissance and highlights the Old Masters’ innovative paint preparation methods.
Why It Matters
The implications of this research extend beyond art appreciation; they provide new insights into the historical practices of painting and potentially improve conservation methods for classic artworks. By understanding the materials used, art historians and conservators can enhance the preservation of invaluable pieces while also enriching the narrative of art history.
Key Developments
- Study Publication: The research, which details the use of proteins in oil paintings, was published in the journal Nature Communications.
- Intentional Use of Egg Yolk: Previous traces of protein found in artworks were often dismissed as contamination, but this study suggests they were likely added for specific benefits.
- Chemical Benefits: Egg yolk enhances paint properties by improving color intensity, drying times, and resistance to environmental conditions.

Insight from Researchers
Ophélie Ranquet, a study author from the Karlsruhe Institute of Technology, emphasized that historical sources on this topic are scarce. Their findings reveal that even small amounts of egg yolk can significantly affect oil paint properties. "The inclusion of egg yolk can lead to substantial changes, including improved aging characteristics,” she noted.
Paint Comparison
Oil paint, primarily made from linseed oil, allows for richer colors and smoother transitions compared to ancient tempera, which blends egg yolk with water and pigments. Egg yolk adds beneficial antioxidants, which help prolong the integrity of the paint. Researchers recreated paint using egg yolk, distilled water, linseed oil, and popular pigments, lead white and ultramarine blue, observing improved viscosity and resistance to humidity.
Historical Context
Leonardo da Vinci’s “Madonna of the Carnation” illustrates the potential effects of insufficient pigment quantities in oil paint, leading to wrinkling. Ranquet suggested that the addition of egg yolk could mitigate this issue, allowing for better overall results. Observations from Botticelli’s “The Lamentation Over the Dead Christ” revealed traces of proteins typically dismissed as contamination but may indicate an intentional incorporation of egg yolk.
Scholarly Support
Maria Perla Colombini, an analytical chemistry professor, praised the study for its novel insights into classical painting methods. She stated that understanding the use of egg yolk not only sheds new light on art techniques but also opens avenues for artwork preservation and art history comprehension.
Context & Previous Events
Historically, the use of oil paint emerged in Central Asia during the seventh century and gained popularity throughout Northern Europe and Italy during the Renaissance. The study’s findings provide a fresh perspective on how these materials were utilized by artists known for their exceptional craftsmanship. The revelation that egg yolk may have played a crucial role in the oil paints of the Old Masters invites further exploration and appreciation of their artistry.
