Limelight

A homemade limelight made by heating calcium hydroxide (slaked lime) in a stove burner. It is not as bright as a real limelight.

Limelight (also known as Drummond light or calcium light)[1] is a type of stage lighting once used in theatres and music halls. An intense illumination is created when an oxyhydrogen flame is directed at a cylinder of quicklime (calcium oxide),[2] which can be heated to 2,572 °C (4,662 °F) before melting. The light is produced by a combination of incandescence and candoluminescence. Although it has long since been replaced by electric lighting, the term has nonetheless survived, as someone in the public eye is still said to be “in the limelight.” The actual lights are called limes, a term which has been transferred to electrical equivalents.

History

The limelight effect was discovered in the 1820s by Goldsworthy Gurney,[3][4] based on his work with the "oxy-hydrogen blowpipe," credit for which is normally given to Robert Hare. In 1825, a Scottish engineer, Thomas Drummond (1797–1840), saw a demonstration of the effect by Michael Faraday and realized that the light would be useful for surveying. Drummond built a working version in 1826, and the device is sometimes called the Drummond Light after him.

The earliest known use of limelight at a public performance was outdoors, over Herne Bay Pier, Kent, on the night of 3 October 1836 to illuminate a juggling performance by magician Ching Lau Lauro. This performance was part of the celebrations following the laying of the foundation stone of the Clock Tower. The advertising leaflet called it koniaphostic light, and announced that: "the whole pier is overwhelmed with a flood of beautiful white light."[5][6] Limelight was first used for indoor stage illumination in the Covent Garden Theatre in London in 1837 and enjoyed widespread use in theatres around the world in the 1860s and 1870s.[7] Limelights were employed to highlight solo performers in the same manner as modern followspots (spotlights).[8] Limelight was replaced by electric arc lighting in the late 19th century.
