Century Dictionary and Cyclopedia
    • n scorification In assaying, a method of assay of the precious metals, performed by fusion of the ore with metallic lead and borax in a so-called scorifier. In this operation, the silver with the gold is taken up by the lead, the superfluous lead and the base oxids being separated in the form of a slag or scoria. The metallic mass obtained is afterward treated by the cupellation process to separate the gold and silver.
    • n scorification In metallurgy, the treatment of a metal with lead in the refining process. Copper intended for rolling into sheets is sometimes thus treated in order that traces of antimony and other foreign metals may be removed. These combine with the oxid of lead, which rises to the surface of the molten copper in the form of a slag or scoria, which is then skimmed off before casting.
