Video: The Alchemical Symbol Hidden in Egyptian Blue - Paul Ferguson - 12-20-2025
"Egyptian Blue—the world’s first synthetic pigment—glows under infrared light. Scientists discovered it emits near-infrared luminescence… almost like a hidden signal. Why did the Egyptians create a pigment that reacts to invisible light? Some historians think it symbolized rebirth, others suspect ritual energy. But the strange part? Modern sensors can detect traces of it thousands of years later. A color… that refuses to die."
