- Noun:
- The foundry added spiegel to the molten steel to improve its quality.
- Spiegel is valued for its dual function as a deoxidizer and a manganese additive.
Advanced Usage
- Technical/Industrial Context: The term is almost exclusively used in metallurgy and steel production. It is a specific material term rather than a common word.
