An increased interest in chemistry led to experiments to produce fire by direct means on this splinter. Learn More in these related Britannica articles:. The head of the strike-anywhere match contains all the chemicals necessary to obtain ignition from frictional heat, while the safety match has a head that ignites at a match higher temperature and must be struck on a specially prepared surface containing ingredients that pass ignition across to the head. Before the invention of matches, it was common to use specially made splinters tipped with some combustible substance, such as sulfurto science a flame from one combustible source to another.

The first friction matches were invented by John Walker, an English chemist and apothecary, whose ledger of April 7,records the first sale of such matches. Other early matches, which could be both inconvenient and unsafe, involved bottles containing phosphorus and other substances.

This substance is found in the head of strike-anywhere matches and in the striking surface of safety matches. There are two main types of modern friction matches: 1 strike-anywhere matches and 2 safety matches. Economic conditions between and seem to have favoured the manufacture of matches as an industrial proposition, although sciehce first suppliers fell back on nonphosphoric formulas—i.

See all videos for this article A match consists of three basic parts: a head, which initiates combustion; a tinder substance to pick up and transmit the flame; and a handle. Sciencd exclusive access to content from our First Edition with your subscription.

Nonphosphoric friction matches were being made by G. Modern safety matches usually have antimony sulfide, oxidizing agents such as potassium chlorate, and sulfur or charcoal in the he, and red phosphorus in the striking surface.

This consisted of a glass bead containing acid, the sfience of which was coated with igniting composition. In addition to the phosphoric igniting agent, three other main groups of chemicals are found in the match: 1 oxidizing agents, such as potassium chloratewhich supply oxygen to the igniting agent and the other combustible materials; 2 binders, such as animal glue, starches and gums, and syntheticswhich science the ingredients and are oxidized during combustion; post-combustion binders, such as ground glasswhich fuse and hold the ash together, must also be used; and 3 inert materials, such as diatomaceous earthwhich provide bulk and regulate the match of reaction.

The substance commonly used for obtaining combustion at the temperature of frictional heat is a compound of phosphorus.
