## Common ground
All options refer to decorative glass items known as mosaic balls, typically used in art, landscaping, or interior design.
## Options at a glance
**7013.10 – Glass ceramics**
- **Defining trait:** Made from glass-ceramic materials, which are heat-resistant and durable due to crystalline structure.
- **Typical examples:** Heatproof decorative spheres, industrial-grade mosaic balls.
- **Best fit when:** The ball is designed for high-temperature environments or needs exceptional durability.
**7013.9X – Other glassware**
- **Defining trait:** Standard glass construction without ceramic crystallization; more common and less heat-resistant.
- **Typical examples:** Decorative garden balls, craft mosaic spheres, standard indoor ornaments.
- **Best fit when:** The product is for general decorative use, not exposed to extreme heat or stress.
## Key differences
| Feature | 7013.10 – Glass ceramics | 7013.9X – Other glassware |
|---------------------|-------------------------------|----------------------------------|
| Material structure | Crystalline (glass-ceramic) | Amorphous (standard glass) |
| Heat resistance | High | Low to moderate |
| Typical use | Industrial, outdoor, high-stress | Indoor, decorative, craft |
## How to choose
- Is the ball made from heat-resistant, crystalline glass-ceramic material? → 7013.10
- Is it standard glass used for decoration or crafts? → 7013.9X
## Overlaps & pitfalls
Some mosaic balls may appear similar but differ in material; if unsure, check manufacturer specs. The term "glassware" is broad—ensure it’s not a ceramic composite. If the product has both decorative and heat-resistant traits, prioritize **main function**: use 7013.10 for heat resistance, 7013.9X for decoration
