Making FireMany different techniques exist to make fire. The oldest use a fire drill (rotating stick) or a stone containing iron. A flint alone doesn't product incandescent sparks. Those methods are from the Paleolithic ages. They are difficult to use in a damp atmosphere. Friction This method consists of rubbing a hard wooden stick (for example some poplar) sharpened to a point, sometimes using a fire bow, on a hollowed piece of soft wood (for example some fig wood). The heat produced is used to ignite tinder. Percussion To produce sparks, you must hit a hard stone, for example a flint, on another containing iron such as pyrite or marcassite. Sparks with this method must be immediately in contact with tinder. Modern methods Matches The invention of matches date from the nineteenth century, but the word matches from about 1200. Lighters Cigarette lighters combine a flint with fuel, and can produce adjustable flames. Pelle feu Il s'agit d'une rsistance lectrique sur laquelle on pose directement des bches dans un foyer. Lorsque la rsistance est porte au rouge, la chaleur communique au bois permet de dclencher sa combustion. Un support permet la rsistance de ne pas tre en contact direct avec le sol. Solar This uses a concave mirror to focus the Sun's rays on some tinder.
