Match boxes

The modern equivalent of this sort of match is the simple fuse, still used in pyrotechnics to obtain a controlled time delay before ignition. The original meaning of the word still persists in some pyrotechnics terms, such as black match (a black powder–impregnated fuse) and Bengal match (a firework producing a relatively long-burning, coloured flame). But, when friction matches were developed, they became the main object meant by the term.
Matches also appeared in Europe by about 1530,yet the first modern, self-igniting match was invented in 1805 by K. Chancel, assistant to Professor Louis Jacques Thénard of Paris. The head of the match consisted of a mixture of potassium chlorate, sulfur, sugar, and rubber.
They were ignited by dipping the tip of the match in a small asbestos bottle filled with sulfuric acid. This kind of match was quite expensive and its usage was dangerous, so Chancel's matches never gained much popularity.
Historically, the term match referred to lengths of cord, or later cambric impregnated with chemicals, and allowed to burn continuously.These were used to light fires and set off guns and cannons. Such matches were characterised by their burning speed, e.g. quick match and slow match; depending on their formulation, they could provide burning rates of between, typically, 1 second and 15 seconds per centimetre.
