Tekhelet and Nanotechnology
According to a new paper published in the Journal of the American Chemical Society the ancient pigment known as Egyptian blue may have important new applications in nanotechnology. Researchers at the University of Georgia in Athens, Georgia in the US were surprised to discover that Egyptian blue breaks into thin nanosheets, 1/1000th the width of a human hair which could be printed using ordinary ink-jet printer techniques. This along with other Egyptian blue properties may have important applications in medical science, telecommunication and lasers.
Blue was the color of the heavens, the Phoenix, the primordial flood and the Nile. Egyptian blue spread quickly throughout the Greco-Roman world. The secret of its manufacture was lost during the fourth century A.D. and rediscovered more than 1400 years later by Sir Humphrey Davy of England.
