(b) Huge fragment of slag with white accumulations of authigenic phases (indicated by the arrows). (c) Small (several cm in diameter) fragments of slag with a vesicular margin and a massive center. (d) Scoriaceous material with fragments of crucible.

Textures of slags from the witochowice waste dump. a) Granular texture of phase assemblage 1, consisting of red spinel embedded in matrix consisting of anhedral melilite, zincite and willemite. Optical image. (b) The same as (a), BSE image. (c) Texture of phase assemblage 4, with euhedral prisms of pyroxene embedded in melilite matrix. Optical image.
