Below is comparison of characteristics between the most common sauna stone gabbro-diabase and Black sauna stone.

Density

  • Gabbro 2790-3300 kg/mЗ
  • Black sauna stone 4500 kg/mЗ

Black sauna stone has low thermal expansion coefficient. Therefore, it will not crack in the process of multiple heating and cooling. The life cycle of chrome ironstone is 2-3 times longer than that of gabbro.

Thermal capacity

  • Gabbro 0.79 kJ / kg oC
  • Black sauna stone 92 kJ / kg oC

 

This enables Black sauna stone to accumulate warmth more efficiently for further emission. This, in its turn, allows the sauna to be more energy-efficient. Experiences show that the use of firewood sinks to 20-30% compared to a stove filled with gabbro-diabase.

ATTENTION: the use of Black sauna stone is forbidden in electric sauna stoves!
