Blue light (pyrotechnic signal)

Blue light is an archaic signal, the progenitor of modern pyrotechnic flares. Blue light consists of a loose, chemical composition burned in an open, hand-held hemispherical wooden cup, and so is more akin to the flashpan signals of the Admiral Nelson era than the modern, encased signal flares, often launched by mortar or rifle and suspended by parachute. Widely used during the eighteenth and nineteenth centuries for signaling by the world's military forces, and for general illumination in the civilian sector, blue light was remarkable for its use of poisonous arsenic compounds (realgar and orpiment), which contributed to its replacement by safer flares in the early twentieth century.
==Blue light (nickname)==
"Blue light" was a derisive nickname given to military officers of the 18th and 19th centuries, whose evangelical Christian zeal burned as brightly as its namesake signal, to the chagrin of those less ardent who were subject to the perceived ostentatious piety.〔Gareth Atkins, review of ''Evangelicals in the Royal Navy, 1775-1815: Blue Lights and Psalm-Singers'' by Richard Blake (review no. 799) accessed Dec. 24, 2011 at www.history.ac.uk/reviews/review/799〕 Confederate Gen. Stonewall Jackson carried the nickname "Old Blue Lights" during the American Civil War because of his overt religiosity.〔poem ''Stonewall Jackson's Way'' pub. Martinsburg, Sept. 13, 1862 accessed Dec. 24, 2011 at www.encyclopediavirginia.org/media_player?mets_filename=evm00001984mets.xml〕
