The slag or dross that remains after the smelting of metal from an ore.
The like stuff is in Anacharsis: hot metal; full of scoriae, which should and could have been smelted out, but which will not.
Rough masses of rock formed by solidified lava, and which can be found around a volcano's crater.
To the south lay broken shapes of scoria in a lava bed as far as the eye could see.
Borrowed from Latin scōria, from Ancient Greek σκωρία (skōría), from σκῶρ (skôr, “dung”).
