Buying Guide
What type should you choose?
- Fire glass vs lava rock: Fire glass offers a reflective surface and brighter flame visuals; lava rock delivers a natural, rustic look and can retain heat differently.
- Color and finish: Reflective finishes (like cobalt blue or Pacific Blue) amplify flame aesthetics; neutral beiges blend with many decors.
How large should the pieces be?
- Smaller pieces create denser coverage and spark more sparkle; larger pieces look more natural and fill space quickly.
What about heat safety and maintenance?
- All items listed are designed for elevated temperatures typical of fireplaces and fire pits. Keep combustible materials away and periodically clean soot buildup for best appearance.
Sizing and installation tips
- Spread stones or beads evenly to avoid flame quenching and to maximize heat distribution.
- Use a compatible fire pit burner system and verify that the fire glass or stones are rated for the intended gas type (propane or natural gas).
