Pumice and scoria

Hekla pumice is a lightweight, chemically inert, porous stone of volcanic origin created by a sicilic explosive eruption about 3000 years ago. Iceland's primary pumice resources are in the southern part of the country. The Grímsnes scoria is a porous, chemically inert, dark colored volcanic rock formed by an effusive lava eruption about 5-6000 years ago in the Grímsnes area. Hekla Pumice and Grímsnes Scoria are a natural resource, porous aggregates that have excellent insulating properties and high particle strengths that makes this product excellent for various uses in industry and construction.
