Gelatin in Matchsticks

What is actually inside a matchstick head?

The answer: gelatine always! Each matchstick head consists of a complex chemical mixture containing technical gelatine. The role of the gelatine is, when the mixture is elutriated, to bind the various chemicals together. In addition to its binding power gelatine has a further advantage: when the reaction mixture is foamed, pores form within the matchstick head, thus making ignition possible.
