kaariuuneissa

Kaariuuneissa are traditional Finnish wood-fired ovens, often found in saunas and cottages. The name "kaariuuneissa" translates roughly to "arch ovens" in English, referring to the characteristic arched construction of the combustion chamber. These ovens are typically built from stone and mortar, designed to retain heat for extended periods.

The primary function of a kaariuuni in a sauna is to heat the sauna stones, which then radiate heat into the room. Water is ladled onto these hot stones to produce steam (löyly), a crucial element of the Finnish sauna experience. The design of the kaariuuni is optimized for efficient wood combustion and heat transfer to the stones.

Beyond saunas, kaariuuneissa can also be used for baking bread and other dishes, utilizing the residual heat after the sauna session. The slow, even heat provided by these ovens makes them ideal for this purpose. Building and maintaining a kaariuuni requires specific knowledge and craftsmanship, often passed down through generations. Their enduring popularity in Finnish culture highlights their effectiveness and aesthetic appeal as a central feature of traditional Finnish living spaces.
