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.

The Döbereiner's lamp is considered as the first commercial application of heterogeneous catalysis[1] and was commercialized for lighting fires and pipes. The world's largest manufacturer of these lighters was Heinrich Gottfried Piegler from Schleiz in Thuringia (Germany).[2] It is said that in the 1820s over a million of the "tinderboxes" were sold.[3]

Examples of the lighter are exhibited in the Deutsches Museum and in the old pharmacy at Heidelberg Castle.
