The tip includes a variety of phosphorus sesquisulfide and you will potassium chlorate. Phosphorus sesquisulfide was an incredibly activated, non-dangerous chemical substances included in host to white phosphorus. It is effortlessly ignited from the heat away from rubbing against good crude skin. The latest potassium chlorate offers the oxygen needed for combustion.
