Black vulcanite is a lightly granulated, dark gray stone. When wet, the stone turns bright black, making it look great with selected HARVIA heaters.
The volcanic origin of the stone dates back approximately 2,000 million years. Due to its structure and composition, vulcanite is a good choice as a stone for sauna heaters because it is hard and durable.
Suitable for use with electric heaters as main stones and as top stones with wood-burning heaters.
Features:
- Split stones accumulate a lot of heat, so the water poured on them evaporates effectively, emitting a lot of steam in the sauna;
- Split stones are easy to stack and they ensure good air circulation;
- Excellent resistance to heat fluctuations and excellent thermal conductivity;
- Color and stone type: Dark gray vulcanite;
- Stone size 5-10 cm, Box weight 20 kg;

Before using the stones for the first time, it is recommended to wash them to remove stains or dust that may cause an unpleasant odor during the first use of the heater.
