Definition

1. Noun:
   • Crucible: A heat-resistant container, typically made of ceramic or metal, used for melting metals, ores, or other materials at very high temperatures, especially in a furnace or foundry.
   • Pot furnace / Furnace pot: A vessel designed to withstand intense heat within an industrial furnace or kiln.

Usage Examples

• Noun:
  • Nhà khoa học đặt kim loại vào trong nồi lò. (The scientist placed the metal into the crucible.)
  • Nồi lò trong xưởng đúc phải chịu được nhiệt độ cực cao. (The crucible in the foundry must withstand extremely high temperatures.)
  • Họ cần thay thế chiếc nồi lò cũ trong lò nung. (They need to replace the old furnace pot in the kiln.)

Advanced Usage

• In metallurgy and chemistry, a "nồi lò" is essential for processes like smelting, fusion, and chemical analysis requiring high-temperature containment.
• The term is technical and primarily used in industrial, scientific, or crafting contexts (e.g., metalworking, glassmaking, chemistry labs).

Variants and Related Words

• Lò nung (n): Kiln, furnace. The heating chamber or apparatus in which a "nồi lò" is used.
• Nồi nấu kim loại (n): Metal melting pot. A more descriptive term for a crucible used specifically for melting metals.

Synonyms

• Crucible: The direct and most accurate equivalent.
• Melting pot: A container for melting materials (common general term).
• Vessel: A general term for a container, specified here as one resistant to high heat.

Notes on Usage

• "Nồi lò" is a specialized technical term. In everyday conversation, it is not commonly used. The simpler word "nồi" means a generic pot or cooker (e.g., rice cooker, cooking pot) and is not heat-resistant in the industrial sense of a "nồi lò".
• The reference definition "creuset" is the French word for "crucible," confirming its technical nature.
