Davy lamp Davy lamp The Davy lamp is a safety lamp for use in flammable atmospheres, invented in 1815 by Sir Humphry Davy. It consists of a wick lamp with the flame enclosed inside a mesh screen. It was created for use in coal mines, to reduce the danger of explosions due to the presence of methane and other flammable gases, called "firedamp" or "minedamp." Davy's invention was preceded by that of William Reid Clanny, an Irish doctor at Bishopwearmouth, who had read a paper to the Royal Society in May 1813. The more cumbersome Clanny safety lamp was successfully tested at
Döbereiner's lamp Döbereiner's lamp Döbereiner's lamp, also called a "tinderbox" ("Feuerzeug"), is a lighter invented in 1823 by the German chemist Johann Wolfgang Döbereiner; the lighter is based on the Fürstenberger lighter and was in production until ca. 1880. In the jar, similar to the Kipp's apparatus, zinc metal reacts with dilute sulfuric acid to produce hydrogen gas. When a valve is opened, a jet of hydrogen is released onto a platinum sponge. The sponge catalyzes a reaction with atmospheric oxygen, which heats the catalyst and ignites the hydrogen, producing a gentle flame. It was commercialized for lighting fires and pipes. It's
