This manual rubbing action creates a spark due to cerium's low ignition temperature between 150–180&#160;°C (302–356&#160;°F). Any material that is harder than the rod itself may be used to produce sparks. Though the striker must have a sharp corner, sharp edge, or a knurled surface in order to produce sparks, carbon steel is not required. The idea that carbon steel is needed to produce sparks from a ferrocerium rod is an oft repeated myth, though carbon steel does make the spark more prevalent when striking. <sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">&#91;</span>6<span class="cite-bracket">&#93;</span></a></sup> </p><p>Ferrocerium is most commonly used to start <a href="/wiki/Bunsen_burner" title="Bunsen burner">Bunsen burners</a> and <a href="/wiki/Oxy-fuel_welding_and_cutting" title="Oxy-fuel welding and cutting">oxyacetylene welding torches</a>.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">&#91;<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.
