dinitro-benzol; this substance, even when in contact with red-hot metals,
is as harmless as wax, while at the same time it is unaffected by water;
hut with a sufficiently strong initial lighting it has considerable explosive
power.
Among explosives are also to be reckoned match-cord, percussion caps
and cartridges, and also fireworks, which last are chiefly manufactured
for use in the arn^.
All kinds of explosives, whether for public or private requirements, are
for the most part manufactured in the country, and the supply
practically corresponds to the demand. The value of imports and exports
respectively in 1913 were 699 000 and 570 000 kronor.
The Table 94 affords an idea of the development of the gunpowder and
explosives industry in Sweden since 1866.
In 1912 there was, in addition, 1 match-cord and fuse factory, employing
18 workmen; the value of the total output was estimated at 96 000
kronor. Ammunition and cartridge factories also existed to the number of 8,
employing, 590 workmen and producing goods to a value of 2 964 000
kronor.
As already mentioned, the Swedish State possesses the powder factory
of Åker, Södermanland Län, and, in addition, two ammunition factories,
.Marieberg, near Stockholm, and Karlsborg in Skaraborg Län.
Dyes and Paints.
No coal-tar dyes are made in Sweden, but the coal-tar and other dyes
imported are used for making drop-colours, colours soluble in spirit or water, and colour
compositions, which can be applied directly to the dyeing of both cotton and
wool. Of the colouring matters obtained in the country may be mentioned
lampblack, reddle, chalk, umber or ochre of different shades, etc.
Lampblack is prepared by an incomplete combustion of resin, wood, and
refuse from the manufacture of resin, tar, and pitch, the soot which is thereby
formed being collected; it can also be obtained by grinding charcoal to a fine
powder.
