FROM SHOVELLED PILES OF ORE TO IRONWORKS
Peasants had been smelting lake and bog iron
ore hundreds of years before the first lake ore works were
founded in Juankoski in 1746. Hauling lake ore was at its peak
from the 1860's to 1880's, after which it gradually diminished
only to come to a complete halt in the 1910's. Extensive
amounts of lake ore were last hauled during the Continuation
War in 1942-1944, when Vuoksenniska Ltd. hauled ore in
northern Savo. They wanted to obtain manganese, and
substantial amounts could be found in limonite.
A long-stemmed collecting net was employed for
hauling ore from a lake. The ore was then rinsed through a
sieve to remove most of the sand and debris. Afterwards, it
was tipped onto a crate balanced on an ore raft or water
sledge. As the day drew to an end, the raft was pushed ashore,
and the ore was shovelled into a heap - a heap of ore was
known as a 'rutnikka' in colloquial language. It was possible
to haul two tons of ore a day.
Later, the ore was transported to an iron
furnace or ironworks. During the summer, ships or large boats
were used, whereas sleighs would be employed in wintertime.
Hauling and tarnsporting ore provided many inhabitants from
remoter areas wiht a welcome opportunity for extra earnings.
In addition to lakes, peasants also hauled ore
from bogs. Their blast furnaces were often situated at the
edge of a bog, many of which still retain names deriving from
ore hauling a hundred years ago. Examples include Rautamullansuo
('Iron soil bog') or Hölmäsuo ('Ore bog'). Lake and
bog iron ore precipitate continuously, making it possible to
be hauled every twenty years from the same location.
IRONWORKS
The first lake ore works was founded in 1746
at Juankoski. After Finland’s incorporation into Russia in
1809, importing ore from Sweden became more difficult. As a
result, it became vital to find alternative sources for raw
materials, and attention was drawn to substantial resources of
lake and bog iron ore.
Nearly fifty lake ore works rose in eastern
and central Finland. Three ironworks were founded in southern
Savo: Haapakoski Works (1842-); Huutokoski Works (1858-1877);
and Oravi Works (1868-1901). Additionally, there was a
bloomery furnace in Porsaskoski within the rural commune of
Pieksämäki (1838-1885). Since the latter half of the 19th
century, the lake ore works produced almost 80 per cent of
Finland’s iron.
Nikolai Putilov, a businessman from St.
Petersburg, owned all three of the ironworks in 1860-1870.
They produced raw materials for Putilov’s iron and steel
foundries in St. Petersburg, which manufactured railway rails,
locomotives, carriages and cannons for the Russian Empire. The
iron that was smelted in Savo was transported to St.
Petersburg in wintertime in lines formed by dozens of sleighs;
after the Saimaa Canal was completed boats were used in the
summers. The iron works created additional employment
opportunities for haulers, charcoal burners and horsemen, and
soon became self-sufficient communities with their own schools,
shops, churches and graveyards. They offered a livelihood for
hundreds of landless people, but also attracted farmers
seeking an easier living.
Three factors contributed to the end of the
heyday of iron works: Russia’s customs policies had become
tighter with an interest in protecting its own iron industry;
newer and more effective iron manufacturing methods were found;
and quarrying rocky ore became easier following the
development of drilling machines and explosives. Many iron
works found a new opportunity in the wood processing and
engine works industries.
