Notes on Usage
- "Muội lò" is a compound noun. The core word "muội" by itself generally means soot or carbon black. The addition of "lò" (furnace, kiln) specifies its origin.
- In modern technical English, the specific substance would often be named directly (e.g., zinc oxide fume, furnace dust) rather than using the translated archaic term "cadmia."
