Charcoal pile in HulthorvaShow map
Experience how charcoal was made in the old days. In Hulthorva there has been a tradition to set up and light up a charcoal pile, a sort of pile that burns wood slowly with the help of limited oxygen feed and in turn create charcoal.
During the cultural day in Hulthorva the charcoal pile is built and filled with 30-35 cubic meter wood that will turn in to charcoal within 4-5 days.

However, it can be tricky to keep the fire at a good level to keep the charcoal pile burning down completely. That is why 24 hours surveillance is required.
History about the charchoal pile:
Charcoal burning started over 1000 years ago when fuel for the iron industry was needed. The thought behind the charcoal pile was to prevent the wood to just burn into ashes.

The heat is regulated with the help of controlled feed of oxygen beneath the charcoal pile.
