A team of engineers successfully recreated the 5,000-year-old Egyptian Blue pigment, revealing its variable recipes and unique optical, magnetic, and biological properties, which could have modern technological applications such as fingerprinting and counterfeit-proof inks.
Researchers from Washington State University and partners have successfully recreated Egyptian blue, the world's oldest synthetic pigment, using ancient techniques involving silica, copper, calcium, and sodium carbonate heated at high temperatures. Their work reveals complex microstructures and the importance of cooling rates in achieving vibrant colors, with modern applications in security, biomedical imaging, and materials science. The recreated pigment is now displayed in a museum exhibit, shedding light on ancient craftsmanship and contemporary scientific relevance.
