Dunite for Electric Sauna Heaters (20 kg) (50-90mm)

Deep effusive rock that is purified naturally by fusion. The main mineral is olivine (forsterite, peridot, chrysolite), one of the most refractory natural compounds. Dunit has great heat capacity and thermal resistance. It offers all the features of a high quality sauna stone. Dunite does not emit harmful impurities and has a sanitation-and-epidemiology certificate on its nuclear safety. Finno-Ugric legends say that Peridot, a component of dunite, helps whoever posesses it avoid cardiovascular diseases.
