Brand new heads away from struck-everywhere fits consist out-of two-fold, the tip in addition to foot

The end include a mixture of phosphorus sesquisulfide and potassium chlorate. Phosphorus sesquisulfide are an extremely reactive, non-dangerous chemical utilized in host to white phosphorus. It’s with ease ignited because of the temperatures regarding rubbing up against a crude facial skin. The brand new potassium chlorate provides the clean air necessary for burning. The tip also incorporates powder glass or any other inert filler procedure to increase new friction and you may manage the new burning rates. Animal adhesive can be used in order to bind new chemical together with her, and you will a little bit of zinc oxide may be added to the tip to give it an effective whitish color.
