插圖:The quest for a practical match really be-gan after 1781 when a group of Frenchchemists came up with the Phosphoric Candleor Ethereal Match, a sealed glass tube con-taining a twist of paper tipped with phospho-rus. When the tube was broken, air rushedin, causing the phosphorus to self-combust.An even more hazardous device, popular inAmerica, was the Instantaneous Light Box——abottle filled with sulphuric acid into whichsplints treated with chemicals were dipped.The first matches resembling those_usedtoday were made in 1827 by John Walker, anEnglish pharmacist who borrowed the formulafrom a military rocket-maker called Congreve.Costing a shilling a box, Congreves weresplints coated with sulphur and tipped withpotassium chlorate. To light them, the userdrew them quickly through folded glass paper.Walker never patented his invention, andthree years later it was copied by a SamuelJones, who marketed his product as Lucifers.About the same time, a French chemistry stu-dent called Charles Sauria produced the first' strike-anywhere' match by substituting whitephosphorus for the potassium chlorate in theWalker formula. However, since white phos-phorus is a deadly poison, from 1845 match-makers exposed to its fumes succumbed tonecrosis, a disease that eats away jaw-bones.It wasn't until 1906 that the substance waseventually banned.That was 62 years after a Swedish chemistcalled Pasch had discovered non-toxic red oramorphous phosphorus, a development exploit-ed commercially by Pasch's compatriot J ELundstrom in 1885. Lundstrom's safetymatches were safe because the red phosphoruswas non-toxic; it was painted on to the strik-ing surface instead of the match tip, whichcontained potassium chlorate with a relativelyhigh ignition temperature of 182 degrees centi-grade.America lagged behing Europe in matchtechnology and safety standards. It wasn't un-til 1900 that the Diamond Match Companybough
