TAR BURNING
The great voyages of discovery and colonialism
gave rise to manufacturing wooden ships on a large scale in
the 16th century. Empires battling for the rule of
the seas built vast war and merchant fleets. Tar was required
for protecting wooden elements and cordage, a demand that
central Europe could not meet. In the early 17th
century, the centre of European tar production shifted from
Prussia to Sweden, which was the head state of the Nordic
countries. Tar production became particularly concentrated in
Sweden’s most forested part, Finland. Tar became Finland’s
first world trade product, making the country the most
significant tar producer in the world in the period of wooden
and sailing ships. Saimaa was one of the principal production
areas.
The tar and pitch of Saimaa’s shores brought
money, tobacco, sugar and coffee to Finland, items previously
almost unknown. Tar and pitch formed a steppingstone between
the medieval fur period and the subsequent period of timber.
The wars gave a deathblow to tar burning on Saimaa: Vyborg,
the main port of exportation, was lost to Russia in 1721, and
the export ports of Hamina and Lappeenranta were handed over
in 1743. Ostrobothnia became the centre of tar burning.
Considerable amounts of tar were also required
domestically. Finnish peasants heeded to a rule in woodwork:
"What e’er you do, do with tar". It was also used
as a universal remedy for people and animals alike. Tar
intended for export was burnt in large tar-burning pits,
whereas that for home use could be prepared in a pot or in a
chute pit that had been dug in the ground. In addition to tar,
peasants made extra earnings from its side products, which
included pitch, carbon black and charcoal.
