Crystals of mercury(II) sulfide and several other mercury compounds are deeply colored red, but have no publicly known use in nuclear weapons.. Red mercury is a discredited substance, most likely a hoax perpetrated by con artists who sought to take advantage of gullible buyers on the black market for arms. [1]
It is the most common source ore for refining elemental mercury and is the historic source for the brilliant red or scarlet pigment termed vermilion and associated red mercury pigments. Cinnabar generally occurs as a vein-filling mineral associated with volcanic activity and alkaline hot springs .
Mercury is a chemical element; it has symbol Hg and atomic number 80. ... The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric ...

Red mercury is a hoax substance of uncertain composition purportedly used in the creation of nuclear bombs. Red mercury may also refer to: Red Mercury (newspaper stamp), an Austrian postage stamp; Red Mercury, a film produced in the United Kingdom, first released in 2005; Cinnabar, the bright scarlet to brick-red form of mercury(II) sulfide
Chinese red was originally made from the powdered mineral cinnabar, but beginning in about the 8th century it was made more commonly by a chemical process combining mercury and sulfur. Vermilion has significance in Taoist culture, and is regarded as the color of life and eternity.
red cinnabar (α-HgS, trigonal, hP6, P3221) is the form in which mercury is most commonly found in nature. Cinnabar has rhombohedral crystal system. Crystals of red are optically active. This is caused by the Hg-S helices in the structure. [5] black metacinnabar (β-HgS) is less common in nature and adopts the zinc blende crystal structure (T 2 ...
Erethism, [n 1] also known as erethismus mercurialis, mad hatter disease, or mad hatter syndrome, is a neurological disorder which affects the whole central nervous system, as well as a symptom complex, derived from mercury poisoning.
