No. I don't believe you. Try it. Look. I told you. Dude. That was awesome. This happened because of low ignition temperature. Ignition temperature is the lowest temperature at which a combustible substance starts burning. Lower the ignition temperature, more easily will it catch fire. Now, a match head contains antimony trisulfide and potassium chlorate. Enough. I know how to use it now. No. The match will not light on any surface. The rubbing surface of a matchbox has powdered glass and red phosphorus. On striking the match against it, friction is caused. Friction generates heat, converting red phosphorus to white phosphorus. White phosphorus has a very low ignition temperature. It immediately ignites in air, producing heat and light, thus beginning the process of combustion. The heat produced breaks down the potassium chlorate present in the match head, releasing more oxygen. This oxygen combines with antimony trisulfide which is also in the match head and keeps the flame burning.
