Notes on Meaning
- The word 'bột tan' refers specifically to the processed powder form. The raw mineral can also be called 'tan' or 'talc' in technical contexts, but 'bột tan' emphasizes its powdered state.
- It is important to distinguish it from other powders (e.g., 'bột mì' for flour, 'bột gạo' for rice powder). 'Bột tan' is defined by its source (talc) and its absorbent, soft properties.
