The tip contains a mix of phosphorus sesquisulfide and potassium chlorate. Phosphorus sesquisulfide was an incredibly activated, non-dangerous chemical compounds found in place of light phosphorus. It’s easily ignited because of the temperatures of rubbing up against a harsh skin. The potassium chlorate supplies the oxygen you’ll need for combustion.
