A spark, a flint: How fire leapt to life
[The control of fire was the first and perhaps greatest of humanity's steps towards a life-enhancing technology.]
To early man, fire was a divine gift randomly delivered in the form of lightning, forest fire or burning lava. Unable to make flame for themselves, the earliest peoples probably stored fire by keeping slow burning logs alight or by carrying charcoal in pots.
How and where man learnt how to produce flame at will is unknown. It
was probably a secondary invention, accidentally made during tool-making
operations with wood or stone. Studies of primitive societies suggest
that the earliest method of making fire was through friction. European
peasants would insert a wooden drill in a round hole and rotate it
briskly between their palms This process could be speeded up by wrapping
a cord around the drill and pulling on each end.
The Ancient Greeks used lenses or concave mirrors to concentrate the
sun’s rays and burning glasses were also used by Mexican Aztecs and the
Chinese.
Percussion methods of fire-lighting date back to Paleolithic times,
when some Stone Age tool-makers discovered that chipping flints produced
sparks. The technique became more efficient after the discovery of
iron, about 5000 vears ago In Arctic North America, the Eskimos produced
a slow-burning spark by striking quartz against iron pyrites, a
compound that contains sulphur. The Chinese lit their fires by striking
porcelain with bamboo. In Europe, the combination of steel, flint and
tinder remained the main method of firelighting until the mid 19th
century.
Fire-lighting was revolutionized by the discovery of phosphorus,
isolated in 1669 by a German alchemist trying to transmute silver into
gold. Impressed by the element’s combustibility, several 17th century
chemists used it to manufacture fire-lighting devices, but the results
were dangerously inflammable. With phosphorus costing the equivalent of
several hundred pounds per ounce, the hrst matches were expensive.
The quest for a practical match really began after 1781 when a group of
French chemists came up with the Phosphoric Candle or Ethereal Match, a
sealed glass tube containing a twist of paper tipped with phosphorus.
When the tube was broken, air rushed in, causing the phosphorus to
selfcombust. An even more hazardous device, popular in America, was the
Instantaneous Light Box — a bottle filled with sulphuric acid into which
splints treated with chemicals were dipped.
The first matches resembling those used today were made in 1827 by John
Walker, an English pharmacist who borrowed the formula from a military
rocket-maker called Congreve. Costing a shilling a box, Congreves were
splints coated with sulphur and tipped with potassium chlorate. To light
them, the user drew them quickly through folded glass paper.
Walker never patented his invention, and three years later it was
copied by a Samuel Jones, who marketed his product as Lucifers. About
the same time, a French chemistry student called Charles Sauria produced
the first “strike-anywhere” match by substituting white phosphorus for
the potassium chlorate in the Walker formula. However, since white
phosphorus is a deadly poison, from 1845 match-makers exposed to its
fumes succumbed to necrosis, a disease that eats away jaw-bones. It
wasn’t until 1906 that the substance was eventually banned.
That was 62 years after a Swedish chemist called Pasch had discovered
non-toxic red or amorphous phosphorus, a development exploited
commercially by Pasch’s compatriot J E Lundstrom in 1885. Lundstrom’s
safety matches were safe because the red phosphorus was non-toxic; it
was painted on to the striking surface instead of the match tip, which
contained potassium chlorate with a relatively high ignition temperature
of 182 degrees centigrade.
America lagged behind Europe in match technology and safety standards.
It wasn’t until 1900 that the Diamond Match Company bought a French
patent for safety matches — but the formula did not work properly in the
different climatic conditions prevailing in America and it was another
11 years before scientists finally adapted the French patent for the US.
The Americans, however, can claim several “firsts” in match technology
and marketing. In 1892 the Diamond Match Company pioneered book matches.
The innovation didn’t catch on until after 1896, when a brewery had the
novel idea of advertising its product in match books. Today book
matches are the most widely used type in the US, with 90 percent handed
out free by hotels, restaurants and others.
Other American innovations include an anti-after-glow solution to
prevent the match from smoldering after it has been blown out; and the
waterproof match, which lights after eight hours in water.
