Here’s a summary of the provided text, focusing on the key findings and data:
Key Points:
* Egg Yolk & oil paint: A recent study suggests that adding egg yolk to oil paint can prevent wrinkling, a common issue in older paintings.
* Leonardo da Vinci’s “Madonna of the Carnation”: This painting exhibits wrinkling on the faces of Mary and the child, providing a visible example of the problem. The study suggests Leonardo may have been experimenting with oil paint at the time and hadn’t yet discovered the benefits of egg yolk.
* How Wrinkling happens: Oil paint dries from the surface down, causing wrinkles, especially when there isn’t enough pigment.Egg yolk seems to counteract this.
* Benefits Beyond Wrinkling: Egg yolk also increases resistance to humidity.
* botticelli’s “The Lamentation Over the Dead Christ”: This painting uses both tempera and oil paint, with oil paint used for background elements.
In essence,the study is shedding new light on the techniques of Old Masters like Leonardo and Botticelli,suggesting they may have unknowingly benefited (or not benefited) from the inclusion of egg yolk in their oil paints.
