The Döbereiner’s lamp is a lighter invented in 1823 by the German chemist Johann Wolfgang Döbereiner, the lighter is based on the Fürstenberger lighter. In the jar, zinc metal reacts with a dilute sulfuric acid solution to produce hydrogen gas. When a valve is opened, a jet of hydrogen is released through a platinum sponge causing it to incandesce and the gas igniting.
