Passage: Ancient Egyptian Powder
Crime scene investigators are about to get an assist from the
land of the pharaohs. New research has shown that
a pigment
called Egyptian blue, formulated some 5,250 years ago, can
be used as dusting powder to detect fingerprints on
complicated surfaces. The earliest known synthetic pigment,
Egyptian blue is found in some of the
paint that still colors
ancient statues, coffins, and tomb walls. Modern scientists
were intrigued by this long-lasting tint and figured out its
chemical components decades ago. More recently they
discovered that it emits near-infrared radiation when
exposed
to a certain kind of light.
