## Common ground
All options describe gas stoves based on their primary construction material.
## Options at a glance
**6914 – Made of ceramic**
- **Defining trait:** Constructed primarily from ceramic, often with a smooth, heat-resistant surface.
- **Typical examples:** Ceramic-top gas stoves, induction-compatible ceramic cooktops.
- **Best fit when:** The stove has a solid ceramic surface (not metal), commonly used in modern kitchens for aesthetics and easy cleaning.
**7321.81 – Made of iron or steel**
- **Defining trait:** Built with iron or steel as the main structural material, especially for the cooking surface or frame.
- **Typical examples:** Traditional cast-iron grills, steel gas ranges, heavy-duty commercial stoves.
- **Best fit when:** The stove has a metal base, visible steel or iron components, or is designed for durability and high heat retention.
## Key differences
| Feature | 6914 (Ceramic) | 7321.81 (Iron/Steel) |
|------------------|----------------------|--------------------------|
| Material | Ceramic | Iron or steel |
| Surface feel | Smooth, glass-like | Textured, metallic |
| Heat retention | Moderate | High |
| Common use | Residential, modern | Commercial, rugged use |
## How to choose
- Is the cooking surface made of solid ceramic or glass? → 6914
- Does the stove have visible iron or steel parts (e.g., grates, frame)? → 7321.81
## Overlaps & pitfalls
A gas stove may combine both materials (e.g., ceramic top with steel frame). In such cases, use the **primary functional surface** as the deciding factor: if the cooking surface is ceramic, choose 6914; if metal grates or a steel base dominate, choose 7321.81. The term "made of" refers to the dominant material, not minor components
