- noun 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.
- noun In metallurgy, the treatment of a metal with lead in the refining process.

In every case the alloy is introduced at the moment of pouring, as is the case in the Bessemer or Martin process, taking care to cover the fusion with charcoal in order to prevent the contact with air, together with the use of some kind of a flux to aid in the scorification of the manganese.
If the scorification has been unsatisfactory, the quantity of silver obtained from the slag will be by no means inconsiderable.
Continue the scorification until a film, green when cold, floating on the surface of the button shows that the nickel is beginning to oxidise.
Dry the residue and concentrate the silver in a button of lead by pot method or scorification, according to the amount of stony matter present.

The weight of nickel corresponding to the arsenide got is calculated by multiplying by 0.607; and, similarly, the weight of the cobalt is ascertained by multiplying the loss in the last scorification by
The object of the fusion in a crucible, like that of scorification, is to concentrate the silver in a button of lead which is to be subsequently cupelled; and to retain the earthy and waste matters in the slag.
In some cases this preliminary scorification is advantageous or even necessary: this may be because the lead is hard and impure, or it may be that a very small button of gold is expected.
The scorification assay is performed in a scorifier, which is a shallow open-mouthed dish about 2-1/2 inches across, with a very thick bottom to enable it to withstand the corrosive action of the slag.
The cupellation of large quantities of alloy or of alloys which contain tin, antimony, iron, or any substance which produces a scoria, or corrodes the cupel, must be preceded by a scorification.
