Limelight

Limelight. An oxyhydrogen jet is directed upon a cylinder of quicklime, a portion of which is thus raised to an exceedingly high temperature,. and emits a brilliant white light. The flame may be produced by burning a "mixture of oxygen and hydrogen supplied under pressure to a suitable jet,. or by blowing a jet of oxygen through a flame of burning hydrogen, coal-gas, or alcohol; or by saturating oxygen with vapour of ether or a volatile hydrocarbon, and burning the mixture. The first method is most effective, but both it and the last-mentioned are dangerous if proper precautions are not taken. Coal gas and oxygen, with a "blowthrough" jet, are most commonly used.
