The end include a mixture of phosphorus sesquisulfide and potassium chlorate. Phosphorus sesquisulfide try an extremely activated, non-harmful toxins included in place of white phosphorus. It is effortlessly ignited because of the temperatures from friction up against good harsh epidermis. The fresh new potassium chlorate supplies the outdoors necessary for combustion. The end also incorporates powder glass and other inert filler point to boost the latest friction and you will manage new consuming price.
