Buying Guide
What to consider when choosing decorative rocks for a fire pit:
- Fuel type compatibility: Most listed products are designed for propane or natural gas. Confirm your system before purchasing.
- Color and reflectivity: Glass offers vivid color and brighter reflections; lava rock provides earthy tones and a natural base layer.
- Particle size: Smaller pieces (like 1/4 inch) create a denser glow but may shift with wind; larger pieces stay put more easily but reveal more surface texture.
- Heat tolerance: Premium tempered glass is designed to withstand high temperatures and resist discoloration over time.
- Maintenance: Glass is generally easy to clean with vinegar water; lava rocks may trap soot and require periodic replacement.
- Installation: Ensure an even spread over the burner to avoid hot spots; follow burner manufacturer guidelines for hole clarity and airflow.
