Scoria is also used as rip-rap, drainage stone, and low-quality road metal. Lava Rock Is Scoria Lava rock is a form of igneous rock called scoria that is created by the eruption of volcanoes. Extrusive igneous rocks form when lava cools and hardens at the surface. Like pumice, scoria contains porous vesicles. One of the main uses of scoria is in the production of lightweight aggregate. The rock fragments, often called cinders or scoria, are glassy and contain numerous gas bubbles “frozen” into place as magma exploded into the air and then cooled quickly. Scoria rock is blown out of the top of a cinder volcano as it explodes. The Boral scientists have taken a holistic approach, studying the effects of applying rock dusts to potting mix alone, and in combination with “sweetpit” (a limestone-based, diamagnetic soil preparation) and artificial fertilizers in varying amounts. To give an example of how large these crystals can get, transparent cleavage sheets of pegmatitic muscovite mica were used as windows during the Middle Ages.
