They’re sized and weighed for easy installation and low maintenance, making them a popular choice for homeowners and outdoor-living designers who want an immediate style boost without complicated upkeep.

How do these glass rocks perform in a propane fire pit?

Onlyfire glass rocks are tempered to withstand high temperatures typical of propane and natural gas burners. They won’t burn, melt, or emit soot when used correctly on top of standard burner systems, and their reflective surface enhances visible flame without interfering with burner ports when installed properly.

• Industrial tempering tolerates temperatures up to 1300°F.
• Non-combustible and won’t smoke or produce odors in gas setups.
• Designed to sit above burners—keep flame ports clear for safe operation.
• Reflectivity increases perceived flame size and color vibrancy.

What are the installation and maintenance steps?

Installing the 10 lb bag is simple: pour the glass evenly across your burner bed, avoiding coverage of flame ports. Maintenance is minimal—periodic rinsing with a mild vinegar-and-water solution restores shine and removes dust or residue.

• Pour glass into pit or table to a depth recommended by your burner manual.
• Keep burner holes free of glass to preserve proper flame flow.
• Clean with vinegar and water; air dry before reusing.
• Store unused glass in a dry container to preserve color and clarity.

Which colors and decorative uses are available?

Onlyfire offers single-color options like Platinum, Onyx Black, and Cobalt Blue, plus curated blends such as Aqua Blue & Platinum. Beyond fire pits, the tempered glass makes a durable accent in planters, vases, water features, and aquarium bases where non-toxic, UV-resistant color holds up over time.

• Single tones: Plutinum (Platinum), Onyx Black, Cobalt Blue and more.
• Designer mixes combine multiple hues for a layered, luminous effect.
• Safe decorative uses: indoor planters, pathways, vase fills, water features.
• UV-resistant and non-fading for outdoor exposure.

How does Onlyfire quality compare to cheaper alternatives?

Onlyfire prioritizes uniform size, consistent color, and high reflectivity through controlled manufacturing and testing. Cheaper glass may cloud, chip, or fade; Onlyfire’s tempering and quality checks reduce those issues and deliver long-lasting brilliance season after season.

• Strict size consistency for even burner performance and appearance.
• Tempering reduces risk of cracking under heat stress.
• Batch-tested for color uniformity and reflectivity.
• Backed by Onlyfire’s focus on outdoor-living accessories.
