Matches.—The great use of phosphorus is in the manufacture of lucifer matches. The ordinary ones are composed of a mixture of phosphorus, potassium chlorate, glue, and red lead, the stick is first dipped in parafin, and then into the above paste.

Bryant and May's safety matches, which only strike on the lid, are made of sulphide of antimony, potassium chlorate, and powdered glass. The lid is smeared with red amorphous phosphorus, and ignition only takes place when the potassium chlorate and phosphorus are rubbed together. By using the above mixture, it is found unnecessary to dip the stick in parafin, as it will catch fire from the ignited composition. This action of phosphorus and potassium chlorate may be shown by powdering a few grains of the salt, adding a piece of red phosphorus about the size of a pea, then very carefully folding it up in paper, upon striking it a moderate blow with a stick, a somewhat violent explosion will ensue. Phosphorus is poisonons; it has a singular action on the jaw-bone, which decays away: this is said not to be the case with the amorphous variety.
