    • Slag (Metal) A product of smelting, containing, mostly as silicates, the substances not sought to be produced as matte or metal, and having a lower specific gravity than the latter; -- called also, esp. in iron smelting, cinder. The slag of iron blast furnaces is essentially silicate of calcium, magnesium, and aluminium; that of lead and copper smelting furnaces contains iron.
    • Slag The dross, or recrement, of a metal; also, vitrified cinders.
    • Slag The scoria of a volcano.
    • v. i. & t Slag (Metal) To form, or form into, a slag; to agglomerate when heated below the fusion point.

Century Dictionary and Cyclopedia
    • n slag The earthy matter separated, in a more or less completely fused and vitrified condition, during the reduction of a metal from its ore. Slags are the result of the combination with one another, and with the fluxes added, of the silicious and other mineral substances contained in the ore, and they vary greatly in character according to the nature of the ores and fluxes used. Blast-furnace slags are essentially silicates of lime and alumina, the alumina having usually been present in the ore, and the lime added (in the form of carbonate of lime) as a flux, or as a means of obtaining a slag sufficiently fluid to allow of the easy and complete separation from it of the reduced metal. The slag of iron-furnaces is frequently called cinder.
    • n slag The scoria of a volcano.
    • slag To form a slag, or to cohere when heated so as to become a slag-like mass.
    • n slag A hollow or depression of land.
    • n slag In the puddling process for making wrought-iron, the slag which forms when, as a preliminary step not always taken, air is blown down upon the surface of a charge of melted cask iron in a specially constructed hearth. Silicon is the principal substance removed from the iron, and the slag consists mainly of ferrous silicate.
    • slag In metal: To convert into slag: as, an excess of limestone used as a flux may to a greater or less extent slag the lining of a furnace.
    • slag To cake together as the result of chemical action at a heat lower than that of fusion.
