Unveiling Secrets: X-rays Reveal Leonardo da Vinci's Experimental Mood in the "Mona Lisa"

X-ray analysis of a tiny speck from the "Mona Lisa" has revealed new insights into Leonardo da Vinci's painting techniques. Scientists discovered a rare compound called plumbonacrite in the base layer of the painting, confirming that Leonardo likely used lead oxide powder to thicken and dry his paint. This finding provides scientific evidence for previously hypothesized techniques used by the artist. The research highlights Leonardo's experimental nature and the ongoing potential for further discoveries about his iconic masterpiece.
