Ammunition and cartridge factories were also to be found to the number
of 4, employing 254 workmen and turning out wares to a total value
of 575,000 kronor.

The Swedish Government possesses one powder-factory, Åker, in the
Län of Södermanland, already mentioned, and two ammunition factories:
Marieberg, near Stockholm, and Karlsborg, in the Skaraborg Län.

Dyes.

No coal-tar or aniline dyes are made in Sweden, but manufactures are
carried on out of the aniline and other dyes that are for the most part imported
into the country such as: drop-colours, colours soluble in spirits or water, and
colour compositions, which can be directly applied to the dying of both cottons
and woolens. Of the colouring matters obtained in Sweden itself may be
mentioned: lamp-black, reddle, chalk, umber or ochre of different shades, zinc-white,
white lead, cobalt blue, and vanadic salts for black colour.

Lamp-black is prepared by an incomplete combustion of resin, wood, and
the refuse from resin, tar, and pitch manufacture, the soot thereby formed being
collected.

Bed die, consisting of oxide of iron, is obtained as a by-product in the
working of copper pyrites and in the burning of alum schist. After being washed
in a weak solution of glue and green vitriol, reddle is employed very largely
for coating over the outsides of timberbuilt houses; it is regarded as being very
durable and very instrumental in preserving wood. The reddle from the Falun
copper mine has long enjoyed a high reputation.

Fire-proof paint is prepared in such a way that it deposits on anything
coated with it a layer of silica which is neither ignitible nor fusible, and hence
protects the wood beneath it from the danger of fire. This kind of colouring
matter can be prepared either with the aid of water-glass or by stirring silicious
marl or finely ground asbestos in ordinary water-colours.

The total number of factories under this general heading in 1900 was 46,
employing 130 hands. The turnout was valued at 872,000 kronor.

With regard to coal-tar or aniline dyes, see page 815.

Other chemical-technical factories.

Of the products of these factories may be mentioned: writing-ink, carbonic
acid, fruit-tinctures, asevtine and other antiseptic agents, hair-oils, pomades,
lanoline, lactic acid, sealing-wax, etc. Of the older, better known manufactures
may be mentinned Henrik Gahn’s Amykos-aseptine, in which boric acid and
peppermint-oil are the most efficacious ingredients; of more recent ones we may
for instance mention Stomatol and Salubrine, in the former of which terpineol,
in the latter acetic ether plays the most important part. Amykos-aseptine is, as
well as stomatol and salubrine, a preparation invented in Sweden.

A new industry in Sweden is the manufacture of fluid carbonic acid} it
dates from early in the nineties and is now carried on at three factories, two at
Löfholmen near Stockholm and the third, recently started, at Limhamn in Skäne.
The total turnout in the year 1900 was 4,148 quintals à 197 cwts.
