Summary
Eight African hardwoods of commercial interest (Mimusops djave; Mitragyna ciliata; Celtis mildbraedii; Antiaris africana; Terminalia superba; Daniella ogea; Entandrophragma cylindricum; and Afrormosia elata) were ashed. The percentage ash content of the woods was determined and the ash samples were analysed for soluble base (as K2CO3), Na+, K+, Ca2+, and Mg2+. A link between the densities of the woods and the Ca2+ content of their ash was established.
