Chibrituri

Astazi, dar in 1826 un om inteligent a inventat chibriturile. Iata mai jos textul pe larg:

In 1826, John Walker (1781-1859), an English pharmacist from Stockton-on-Tees, invented the first practical, strike-anywhere, friction match, but refused to patent his creation. He used three-inch splints of wood, tipped with potassium chlorate, antimony sulphide, and gum arabic. The match head was ignited by drawing it through a fold of fine glasspaper. By 1829, similar matches called „Lucifers” were sold throughout London. Their difference was added sulphur to aid combustion, and white phosphorus. Matchmaking workers quickly developed a bone disease called „phossy jaw” from the phosphorus. Phosphorus sesquisulphide replaced the deadly white phosphorus in the strike-anywhere match during the early twentieth century.
