Randan is a commune in the Puy-de-Dôme department in Auvergne in central France.
The place gives its name to Randanite, a soluble silica that occurs as fine earth near Randan and near Algiers.[1] In the late 19th century the official composition of the dynamite at the Poudrerie nationale de Vonges and other French powder works was 75% nitroglycerin, 20.8% randanite, 3.8% Vierzon silica and 0.4% magnesium carbonate.[2]
