INSTANTANEOUS LIGHTS.

Those who are not old enough to remember the time when flint-and-steel

were the implements employed to obtain a light, can have no sufficient

appreciation of the great convenience of "Lucifer" matches. In those

"good old times," it was a regular household care to provide a

sufficiency of tinder, to see that it was kept dry, and that there

was a proper flint "with fire in it." The striking of a light, when

the tinder-box was adequately supplied, was no mean accomplishment;

and the unskilful hand, operating in the dark, would either get no

sparks at all, or send them in a wrong direction, and not unfrequently

strike the skin off the knuckles, in the vain endeavour to set light

to the tinder. Or if the tinder were damp, the sparks would fall upon

it without igniting, and minutes would be spent in holding a pointed

brimstone match to the delusive spark, and blowing at it without

effect. Sometimes the incautious operator, tired with his fruitless

efforts, would sprinkle gunpowder over the tinder, to make it take

fire more readily, and whilst puffing at a long-desired spark, the

gunpowder would explode in his face and nearly blind him. Such were

some of the annoyances, attended by loss of time, that were experienced

in obtaining the same result that is now produced instantaneously, and

much more effectively, by merely rubbing the match against any rough

surface.

Several attempts had, indeed, been made many years ago to supplant

the flint-and-steel and tinder-box, and some of the plans adopted so

closely approach the matches now in use, that we wonder the inventors

did not succeed long since in contriving the very facile means of

striking a light that we now enjoy. Phosphorus and brimstone matches

were first employed for the purpose. The phosphorus was contained in a

bottle placed within a tin case, which also held the pointed brimstone

matches and a piece of cork. The match was dipped into the phosphorus

bottle, and then rubbed on the cork; and the friction excited

sufficient heat to inflame the small quantity of phosphorus adhering

to the match and, to set fire to the sulphur. These phosphorus boxes

answered the purpose very well, but the apprehended danger of using so

inflammable a substance prevented their coming into general use; and

they were much more costly than a tinder-box.

In the next advance, if it may be so called, in the invention of

instantaneous light-producers, phosphorus was altogether discarded,

and a mixture of chlorate of potass, then called oxymuriate of potass,

and sugar was employed. Those substances, when combined, inflame

explosively in contact with sulphuric acid. In applying them for the

purpose of obtaining instantaneous light, they were mixed together in

an adhesive menstruum, into which the ends of small rectangular matches

were dipped. These matches very nearly resembled the "Lucifers" of

the present day. To ignite them, a small bottle containing sulphuric

acid and asbestos was provided, and they were arranged together in

an ornamental taper-stand for the chimney-piece. This apparatus was

not received with much favour, partly on account of injury done by

a careless use of the sulphuric acid, partly because it failed to

act when the acid had absorbed moisture from the atmosphere, but

principally because of its cost.

To obviate the objection arising from the use of sulphuric acid in

open bottles, an ingenious contrivance was adopted, by which each

match contained its own reservoir of acid sufficient for igniting

the inflammable compound. Small glass globules, containing sulphuric

acid, were introduced into the composition of chlorate of potass and

sugar, which, when broken, set fire to the mixture and lighted the

match. These instantaneous lights, which were called _Prometheans_,

were more ingenious than useful, because the trouble of manufacture

rendered them expensive, and the sulphuric acid was more likely to

injure furniture in that form than when a bottle with asbestos was

used. The Prometheans, however, possessed the advantage of portability,

and for occasional purposes they were convenient. In some of the forms

in which the Prometheans were manufactured, the glass globule of acid,

surrounded by its inflammable compound, was attached to the end of a

small stick of sealing-wax, sufficiently large to seal a letter; but

this refinement in instantaneous lights was not much patronized.

Notwithstanding these ingenious attempts to produce light by chemical

action, the flint-and-steel retained possession of the field until

a match was made that ignited by friction alone. The first kind of

friction match was invented in 1832. It consisted of a thin splinter

of dried wood, the top of which was dipped in a mixture of one part

of chlorate of potass, two of sulphide of antimony, and one of gum.

To ignite the match it was necessary to draw it briskly through

sand-paper. These matches required some address to light them, because

much more friction was required than is sufficient to light Lucifers.

The next improvement was the "Congreve" match, in which recourse

was had to the materials previously used, separately, for obtaining

instantaneous lights. Congreve matches were composed of an emulsion

of phosphorus mixed with chlorate of potass, into which the matches,

previously tipped with sulphur, were dipped. These matches were of

the same size and form as the Lucifers now in general use, and they

ignited readily by friction on sand-paper or other rough surface. Their

explosive noise on inflammation, which gave them their name, was the

only apparent difference between Congreves and Lucifers, and their

introduction completely supplanted the flint-and-steel.

The noiseless match, or Lucifer, has, in its turn, driven the Congreve

almost out of use, though for practical purposes the latter was as

effective, and it was less dangerous. The Lucifer matches depend

altogether on phosphorus for their inflammability. Their composition

is an emulsion of phosphorus with glue, nitre, and some colouring

matters. The sulphur matches, after having been tipped with that

composition, are exposed in a warm room until a sufficient quantity of

the phosphorus is evaporated by slow combustion, to leave a film of

glue on the surface to protect the remainder from the action of the

atmosphere. The usual proportions for the compound are, phosphorus

four parts, nitre ten, glue six, red ochre five, and smalt two. The

principle on which the action of Lucifer matches depends, is the strong

affinity of phosphorus for oxygen, of which the nitre with which it

is mixed contains an abundant supply; and by drawing the match across

sand-paper, sufficient heat is excited by the friction to ignite

the phosphorus, and the nitre supplies the oxygen to maintain rapid

combustion.

The manufacture of Lucifer matches is conducted on a very large scale

in this country and on the Continent. It requires several ship loads of

wood to supply the requirements of Lucifer-match makers; and ingenious

contrivances have been patented for cutting it up into splints of the

proper size. For that purpose, after the wood has been reduced to

the required lengths by circular saws, it is cut up into splints by

a number of lancet points, separated from each other as far apart as

the thickness of a match, which pass over the wood and divide it with

great rapidity. The splints are collected into bundles of one thousand,

and each end having been dipped into melted sulphur, they are divided

in the middle by a circular saw.

The Reports of the Juries of the Great Exhibition supply a variety of

statistical details respecting the manufacture of chemical matches,

from which it appears that the quantity made in Austria, in 1849,

amounted to 50,000 cwt.; and that in France, in 1850, the phosphorus

consumed in the manufacture of matches, amounted yearly to 590 cwt.;

and the consumption has rapidly increased since that time. In this

country, it is calculated that eight tons of phosphorus are yearly used

in making matches, the number of which is stated to be 40,000,000 a

day. Large quantities are also imported from Germany, where they are

manufactured so cheaply, that fifty boxes each containing 100 matches,

are sold for fourpence.

The latest improvement in chemical matches is the "Vesta," which

consists of small wax, or stearine tapers, with an igniting composition

at the end, consisting of chlorate of potass and phosphorus. These

Instantaneous Lights are made without sulphur, consequently the

disagreeable smell of the common Lucifer is avoided. The convenience

of smokers has also been consulted in the manufacture of Instantaneous

Lights. The fusees, now so frequently used for lighting cigars, are

composed of thin card-board cut half through, steeped in nitre and with

a small quantity of phosphorus; and the tearing of the paper across

produces sufficient heat to ignite the inflammable card.

Thousands of persons, principally children, are now employed in

the manufacture of chemical matches. The occupation, as at present

conducted, is very unhealthy, for the fumes of the phosphorus produce

a disease of a remarkable kind in the jaw-bone, which often proves

fatal. No cure has yet been found for this peculiar disease, occasioned

by the phosphorus in the state in which it is commonly used. A

preparation of that substance has, however, been made which may be used

without injury, and which possesses the advantage also of being less

dangerously inflammable; but as the red _amorphous phosphorus_, as it

is called, is rather more costly, the manufacturers of Lucifer matches

object to use it.
