Black Lightning
Dense black with silver that yields a mirror-like blue metallic finish or earthy organic tones depending on reduction; work heavily oxidizing, then reduce at the end for the metallic sheen.
Outcomes
-
Dense black with a mirror-like blue metallic sheenWork in a super oxidizing flame throughout, then bathe the piece in a super reducing flame for several seconds at the end to produce the mirror-like sheen.
-
Organic earthy tones (over-reduced)Over-reducing the piece shifts the color away from the metallic finish into an organic, earthy tone instead of the mirror sheen.
-
Dense black with silver, encased in clearEncase Black Lightning with clear for another great effect; works well stretched and in blown work. Anneal thoroughly if heavily encased.
Working notes
- Work super oxidizing throughout the piece, then reduce only at the very end for the metallic sheen.
- Over-reduction produces earthy tones instead of the mirror finish — control reduction time carefully.
- Anneal thoroughly if heavily encased.
