- scoria
- {i} slag, waste material that remains after smelting metal; variety of light lava stone similar to pumice
- scoria
- Scoria forms when blobs of gas-charged lava are thrown into the air during an eruption and cool in flight, falling as dark volcanic rockcontaining cavities created by trapped gas bubbles
- scoria
- The recrement of metals in fusion, or the slag rejected after the reduction of metallic ores; dross
