O Fósforo

O palito de fósforo foi inventado no século XIX, porém a história do palito que mudou a forma de se fazer fogo se iniciou bem antes, em 1669, com a descoberta do fósforo (elemento químico P).

O alemão Hennig Brand, em suas tentativas de transformar metais em ouro, descobriu acidentalmente o elemento ao estudar amostras de urina. O material que obteve brilhava e, por essa razão, Brand batizou a substância de Phosphoros, que quer dizer “aquele que traz a luz, que ilumina”.

Depois da descoberta, vários aparatos químicos para gerar fogo foram desenvolvidos na Europa. Alguns usavam a descoberta de Boyle, outros, hidrogênio, porém eram todos complicados e arriscados. Em 1805, um químico francês chamado K. Chancel criou um palito coberto de clorato de potássio e açúcar. Mas, como era preciso encharcá-lo em ácido sulfúrico para que queimasse, ele não fez muita fama.

Mas então por que colocar esse nome: Palito de Fósforo? Durante muito tempo, o fósforo foi realmente colocado no palito e acendia em qualquer superfície áspera. Na verdade, este tipo de palito ainda está lá, é tradicionalmente encontrado no Reino Unido.
