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 (invented in Basel in 1780; in which hydrogen gas is ignited by an electrostatically generated spark). Döbereiner's lamp 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.
