Lunar Glass
Venus Dark Sea Blue Opal Glass
Deep sea dark blue opal glass; copper-based so requires an oxidizing flame — reduce and it will liver. Stable, rich color throughout working with luminous opal translucency.
Outcomes
-
Rich dark deep-sea blue opal with luminous translucency and substantial opacityMaintain an oxygen-rich oxidizing flame to preserve color; the copper base requires cranked-up oxygen for stable color development throughout working.
-
Livered, degraded color — dull, muddy, or discolored surfaceA reducing or insufficiently oxidizing flame causes the copper-based glass to liver, resulting in undesirable surface degradation.
Working notes
- Copper-based glass — always work in an oxidizing flame; reducing will cause livering.
- Never reduce.
