The end contains a variety of phosphorus sesquisulfide and you may potassium chlorate. Phosphorus sesquisulfide are an incredibly activated, non-poisonous agents found in host to white phosphorus. It is with ease ignited of the temperatures from rubbing against a good rough body. The newest potassium chlorate provides the outdoors required for burning. The end comes with powdered mug or other inert filler thing to increase the new friction and you can handle the fresh burning rate.
