Inorganic matter The inorganic matter present in pulp originates not only from the wood raw material but also from the pulping process. The total inorganic matter in pulp is usually reported as residue on ignition or ash. Ash and its components The procedure used for ignition may cause inorganic salts to decompose. The rate of
