Unveiling Leonardo's Painting Technique: The Secret of the 'Mona Lisa' Revealed

Scientists have used X-rays to analyze a tiny speck of the "Mona Lisa" and discovered that Leonardo da Vinci likely used a unique oil-paint recipe as the base layer for the iconic painting. The research suggests that Leonardo was in an experimental mood when he created the masterpiece, with each of his paintings being technically different. The discovery of a rare compound, plumbonacrite, in the first layer of paint confirms that Leonardo probably used lead oxide powder to thicken and dry his paint. This new insight into Leonardo's techniques is considered significant for the art world and highlights his spirit of constant experimentation as a painter.
