Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'горн' alone, which is a broader term for forge/furnace. 'Ore hearth' is a specific type of 'горн для руды' or 'плавильный горн'.
- Avoid translating 'hearth' as 'очаг' in the domestic sense; here it's a technical 'плавильное устройство'.
Common Mistakes
- Misspelling as 'ore heart'.
- Using it as a verb (e.g., 'to ore hearth').
- Assuming it is a common term in modern engineering.
