Where can you find scoria?

Scoria is common in areas of recent volcanism, such as the Canary Islands and the Italian volcanoes. It is relatively low density due to its vesicles, bu it is not as light as pumice. Also differs from pumice in that it has larger vesicles with thicker walls.

Where does scoria come from?

Scoria forms when magma containing abundant dissolved gas flows from a volcano or is blown out during an eruption. As the molten rock emerges from the Earth, the pressure upon it is reduced and the dissolved gas starts to escape in the form of bubbles.

Where would you find pumice and scoria?

Scoria and pumice are both igneous rocks, produced by the cooling of magma.

How is scoria mined?

The volcanic area, called a cinder cone or a scoria cone, is easy to mine, Bratton said. The rock is porous and can be pushed off the hill, sifted by size and then sold. It comes in different sizes – the boulders aren’t as popular as Bratton expected – so the company rarely has to crush it down to road sand size.
