How do these glass rocks improve the look of a propane fire pit?

• Mirror-like finish intensifies flame reflections
• Uniform 1/2" pieces form an even flame surface
• Available in 12 single colors and several curated blends
• Instant visual upgrade over lava rocks or ceramic logs

Are these fire glass rocks safe for high heat and indoor use?

Yes — the glass is tempered to tolerate temperatures above 1350°F without popping, melting, or releasing odors. That heat resistance and stability make them suitable for both outdoor fire pits and indoor gas fireplaces when used according to burner manufacturer guidelines.

• Safe for indoor fireplaces when following safety instructions
• Keeps burner ports clear for consistent gas flow

How easy is installation and ongoing care?

Installation is straightforward: pour the glass over the burner, keeping burner holes unobstructed. Maintenance is minimal — a periodic rinse with a vinegar-and-water solution restores the original luster if dust or residue appears.

• Keep burner ports visible and clear of glass
• Occasional rinse with vinegar and water to refresh shine
