Stanbroil Fire Glass for Gas Fire Pits and Fireplaces — 10 lb Onyx Black 1/2" Tempered, Reflective

Stanbroil 10-pound tempered 1/2-inch onyx black fire glass is reflective, heat-safe decorative media designed for propane and natural gas fire pits, fireplaces, and outdoor bowls.

Give your gas fire feature a modern, jewel-like finish with these tempered glass beads. Cut to a consistent half-inch size and treated with a premium tempering process, the onyx black glass beads resist heat-related degradation and retain a consistent reflective finish. They replace traditional lava rock or wood for a cleaner, low-residue flame presentation and are suitable for both indoor gas fireplaces and outdoor fire pits.

How does Stanbroil fire glass perform under heat?

These beads are tempered to withstand repeated heating and cooling cycles without cracking, clouding, or breaking down. That tempering also enhances surface reflectivity so flames look brighter and more vibrant against the dark onyx finish.

• Premium tempering prevents thermal shock and reduces breakage.
• Consistent 1/2" bead size promotes even flame patterns and gas flow.
• Reflective onyx finish enhances flame contrast for visual impact.

Is this compatible with my gas fire pit or fireplace?

Stanbroil fire glass is formulated for use with propane and natural gas burners and works in both indoor fireplaces and outdoor fire bowls. It’s not for direct burning on wood or open flames—only for gas-fueled systems or as a decorative bed over the burner components.

• Safe for propane and natural gas systems when installed as a media bed.
• Suitable for replacing lava rocks and gas logs in many setups.
• Not intended as a fuel—do not use with solid-fuel fires.

How easy is installation and maintenance?

Installing the glass is straightforward: clear the burner area, spread an even bed to the manufacturer’s recommended depth, and reinstall burner components if needed. Cleaning is low-effort—remove beads, rinse with a vinegar-and-water solution if necessary, and let dry before returning them to the fire feature.

• Simple spread-and-set installation—no special tools required.
• Rinseable surface for easy removal of dust and residues.
• Store in a dry place to preserve appearance and performance.
