BISOROCK® Edellava (enhanced lava) lava rock from the Eifel
The ejected lava was expanded like foam through water vapor and carbon dioxide and cooled into a mineable deposit in the upper layers.
Lava is a natural volcanic rock that distinguishes itself from all other natural rocks by its unique properties.
After mining, Bisotherm lava rock is carefully broken and classified into different grain sizes.
