- 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
- 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
- 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
- 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
