After extraction of alkali from calcined plant material, the remaining ash is called dead earth, and the source says nothing further can be drawn from it. The designation marks an asserted operational endpoint. It differs from caput mortuum in cohobation, where the residue is reused; the adjective “dead” does not guarantee identical usefulness or composition in every phrase.
