• Scoria is a textural term for macro vesicular volcanic rock.
• It is commonly, but not exclusively, basaltic or andesitic in composition.
•  Scoria is light as a result of numerous macroscopic ellipsoidal vesicles, but most scoria has a specific gravity greater than 1, and sinks in water.
• Scoria, the less silica-rich equivalent of pumice, are vesicular (bubbly) glassy volcanic rock fragments of basaltic to andesitic composition that are ejected during explosive eruptions.
• Scoria is the common product of strombolian eruptions or lava fountains.
• The bubbles are due to the escape of volcanic gases from the magma during the eruption when they are 'frozen' inside the glass.
•  Scoria is typically dark gray to black in color, mostly due to its high iron content. Sometimes, oxidation (of iron) leads to a deep reddish-brown color.
• Is a type of igneous rock formed under pressure during the formation of volcanic cones.
• Scoria formed as lava exploded out of a volcano. 
• Gas bubbles formed inside the lava, and were trapped as the lava cooled and hardened into rock.
• Volcanic cones of scoria can be left behind after eruptions, usually forming mountains with a crater at the summit.
• It is therefore extremely hard and durable yet very porous,
  so it drains water from surface soils extremely well.
• Scoria cones (also called cinder or tephra cones) commonly occur in groups or fields, such as in Crater Flat.
• Crater Flat is a relatively small cinder cone field; some contains hundreds of cones.
• They can be used to reduce the finished weight of any concrete or masonry product by up to 30%.
• They are ideal for specialty applications in the filter and refractory areas where our sand's light weight, excellent insulating and fire refractory properties give the product unique benefits.
• Scoria has very good drainage properties
