Should lead have been present in the sulphide or ore, it remains after a second, or even a third fusion, although proportionately reduced in quantity; and it can only be completely separated in the humid way. It is, therefore, always desirable to select an ore free from lead.
Antimony, Ash of. Syn. Antimony-ash, Calcined’ antimony*; Ci′nis antimo′′nii, Antimo′′nium calcina′tum*, L. Prepared by roasting the common grey sulphide of antimony on an iron plate set under a chimney, to carry off the fumes. The product is a mixture of teroxide of antimony, with some unburnt sulphide, and a little antimonious acid.
Prop., &c. Ash-grey; emetic in small doses. Used chiefly as a cheap substitute for teroxide of antimony by the manufacturers of tartar emetic; also to make metallic antimony.
