Jet Black: An Enigma of Darkness
Jet black is a captivating hue that exudes an aura of mystery and sophistication. Its profound darkness has intrigued scientists, artists, and engineers alike for centuries, leading to a plethora of applications in diverse fields. From the depths of space to the fashion runways, jet black’s enigmatic allure continues to inspire and astound.
Origin of Jet Black
The concept of “jet black” originated from the naturally occurring mineral jet, a variety of lignite coal known for its deep black color and lustrous surface. In the 16th century, the term “jet black” was coined to describe a pigment made from ground jet and was extensively used as a dye and ink.
Scientific Properties of Jet Black
Jet black is characterized by its remarkable absorption properties. It absorbs almost all visible light, reflecting a mere 1% to 2% of the incident light. This profound absorption results in the perception of a deep and intense black hue. Additionally, jet black exhibits exceptional thermal emissivity, radiating heat efficiently.
