LUCIFER-MATCHES.

Illustration: FILLING THE BOXES.

These convenient matches, which have completely superseded the old

apparatus of flint, steel, and tinder-box, may be looked upon as

one of the improvements derived from chemistry, for phosphorus--the

necessary ingredient--till lately sold at half-a-crown an ounce;

such a price would, of course, prevent its being used for so

general a purpose as match-making. But when chemistry devised means

of preparing it on a large scale, and at a low price, then its

application was soon perceived.

Illustration: CUTTING THE MATCHES.

Illustration: FRAME.

Some years ago a kind of match was used, made of chlorate of potash

and sulphuret of antimony, and ignited by drawing through a folded

piece of glass-paper. Another sort was also for a time in use called

“Prometheans,” but far too expensive for general use. They consisted

of strips of paper rolled up, with a little glass cylinder full of

sulphuric acid sealed up in the end of each, surrounded by chlorate

of potash in powder; the end of the match had to be crushed by a

small pair of nippers, and the glass being broken, the sulphuric acid

came in contact with the chlorate of potash, causing it to take fire.

Illustration: DIPPING THE MATCHES.

For making lucifer-matches the wood is sometimes split by hand,

and sometimes by machinery. For those the wood of which is rounded,

a peculiar apparatus is used; it consists of a plate having small

steel cylinders let into it, so that their cutting edges are raised

above the plate, and the wood is struck upon this, and not only

divided, but each piece forced through the cylinders and so rounded.

When cut, the wood is dipped in bundles into melted sulphur, and

afterwards into a composition variously made, but usually consisting

of phosphorus ground up with gum arabic and water, colored either

with red-lead or Prussian blue, and in some cases chlorate of potash

is added. This composition is spread out on a board to about the

tenth of an inch in thickness, and the matches which have been dipped

in sulphur are packed into a frame to the number of about 3000, and

dipped by pressing them on the board spread with the composition, so

that a little is attached to the ends of each match. This is a most

unwholesome and dangerous employment, and water is always at hand,

in case of fire, which is chiefly to be feared in the process of

separating them and filling the boxes when the composition has dried.
