## Key differences
| Material | Texture/Feel | Transparency | Durability | Aesthetic |

| Porcelain | Smooth, glossy | Opaque | Low | Elegant, fragile |
| Ceramic | Matte, rough | Opaque | High | Earthy, handmade |
| Glass | Smooth, cold | Transparent | Moderate | Clean, visible |
| Iron/Steel | Cold, hard | Opaque | Very high | Industrial, durable|
## How to choose
- Is the barrel made of plastic? → 3924.10
- Is it made of wood? → 4419
- Is it glazed and fine (like china)? → 6911.10
- Is it unglazed or matte clay? → 6912.00
- Can you see through it clearly? → 7013.10,7013.4X
- Is it metal and heavy? → 7323.9X
## Overlaps & pitfalls
- Glass and plastic may both be transparent; use "material" not "visibility" as the key.
- Porcelain and ceramic are both ceramics but differ in finish and firing temperature—prioritize glaze and quality.
- No option is vague, but “ceramic” vs. “porcelain” depends on finish: glossy = porcelain, matte/earthy = ceramic.
- If unsure, choose based on the **main material** (e.g., steel over paint or coating)
