Scoria
A variety of Igneous
What is Scoria?
A dark-colored volcanic rock with numerous small cavities, scoria is often used in landscaping, as well as insulation and drainage works. Very similar in properties to Pumice, scoria is heavier and denser and sinks in water, while Pumice floats. It is often scattered to create traction on snow-covered roads.
Uses & Applications
Scoria's light weight gives it many industrial uses. It can be used to make concrete that is one-third lighter than other types of concrete. Since the material is filled with air pockets it acts as an excellent insulator, reducing the costs of heating and air-conditioning. Scoria is also used as a heat absorbent material in barbeques and sauna rocks.
