- to reduce something to cinders
A cinder is a pyroclastic material (lava or magma). Cinders are either intrusive igneous (magma cooled inside the earth) or extrusive igneous (lava cooled outside of the earth). Cinders are similar to pumice, which has so many cavities and is such low-density that it can float on water. Pumice or cinders are used in soap, xeriscaping, mulch, and rock gardens.
CharacteristicsThe following geologic characteristics define a cinder:
UsesCinders have been used on track surfaces and roads to provide additional traction in winter conditions. Cinders are also popularly employed as inorganic mulch in xeriscaping, because of excellent drainage properties and resistance to erosion. In this context, they are referred to frequently with the synonym "lava rock".
ChemistryCinder is composed of 80% Group 4A elements, 18% chalcogens, and less than 2% rare earth elements.
