Ash is the solid remnants of fires. [1] Specifically, ash refers to all non- aqueous , non- gaseous residues that remain after something burns . In analytical chemistry , to analyse the mineral and metal content of chemical samples , ash is the non- gaseous , non- liquid residue after complete combustion.
A crucible and tongs, on a green mat. The ash content of a sample is a measure of the amount of inorganic noncombustible material it contains. The residues after a sample is completely burnt - in contrast to the ash remaining after incomplete combustion - typically consist of oxides of the inorganic elements present in the original sample.

The types of minerals present in volcanic ash are dependent on the chemistry of the magma from which it erupted. Considering that the most abundant elements found in silicate magma are silicon and oxygen, the various types of magma (and therefore ash) produced during volcanic eruptions are most commonly explained in terms of their silica content.
