An incandescent gas mantle, gas mantle or Welsbach mantle is a device for generating incandescent bright white light when heated by a flame. The name refers to its original heat source in gas lights which illuminated the streets of Europe and North America in the late 19th century.
While electric lighting was introduced to theatre stages, the gas mantle was developed in 1885 for gas-lit theatres. "This was a beehive-shaped mesh of knitted thread impregnated with lime that, in miniature, converted the naked gas flame into in effect, a lime-light."
This led to a series of lamps that were originally made to burn kerosene or gasoline. Current models use kerosene, gasoline, Coleman fuel or propane and use one or two mantles to produce an intense white light. Over the years more than 50 million of the lanterns have been sold throughout the world. [2]
