GRISUN Fire Glass for Fire Pit — Pacific Ocean Blue 1/2-inch 10 lb | Polished, Heat-Resistant Decorative Glass

GRISUN Pacific Ocean Blue 1/2" fire glass is an iridescent decorative glass aggregate made to replace lava rock in gas or electric fire pits, offering long-lasting color, heat resistance, and a sparkling flame effect.

These 10 pounds of 1/2-inch fire glass pieces are cut and polished to reflect flame and light, creating a vibrant blue bed for indoor or outdoor fireplaces, fire tables, and decorative displays. Manufactured to resist heat, corrosion, and fading, the glass provides an attractive, low-maintenance alternative to traditional fire media. It is intended for use with propane, natural gas, or electric fire features and can be layered over lava rock for improved gas flow and performance.

How will this fire glass change the look of my fire pit?

The Pacific Ocean Blue glass transforms the flame’s appearance by reflecting light through faceted, polished pieces, producing a lively, jewel-like glow. Colors remain vivid even when heated, so the visual impact is consistent during use.

• Enhances flame color and sparkle with mirror-like reflections.
• Provides a modern, polished aesthetic compared to raw lava rock.
• Uniform 1/2" pieces create an even flame pattern and coverage.

Is this glass safe and suitable for my gas or electric fireplace?

GRISUN fire glass is designed for fireplaces and fire features that use propane, natural gas, or electricity; it does not burn and withstands high temperatures. For best results, place a layer of lava rock underneath the glass to protect burner components and promote correct gas flow.

• Non-combustible, heat-resistant glass that won’t melt or emit fumes.
• Works with indoor and outdoor gas or electric units when installed per manufacturer guidelines.
• Use a lava rock layer beneath the glass for safety and performance.

How much glass do I get and how should I install it?

This package contains 10 pounds of 1/2-inch Pacific Ocean Blue fire glass—enough to cover a modest burner area or top a layer of lava rock for much larger bowls. Installation is straightforward: shut off fuel, place 1–2 inches of lava rock, then spread the glass to the desired depth without burying burners or controls.

• 10 lb bag of 1/2" polished fire glass pieces in Pacific Ocean Blue.
• Typical coverage depends on burner size; combine with lava rock for best results.
• Do not cover burner ports; follow your appliance manual for safe depths.

Will the color last and how do I maintain it?

The glass is engineered to resist fading and corrosion under normal use, so the blue hue and luster remain over time. Maintenance is minimal: cool the unit, remove debris, and rinse or wipe the glass pieces as needed to restore shine.

• Fade-resistant finish keeps colors vibrant through repeated heating cycles.
• Easy to clean—simply rinse, dry, and replace for renewed sparkle.
• Designed to retain heat briefly without glowing or combusting after shutoff.

Who is this for: Homeowners and designers who want an upgrade from traditional lava rock to a modern, reflective fire media will appreciate GRISUN Pacific Ocean Blue fire glass. It’s ideal for people with gas or electric fireplaces, fire pits, or tables seeking a low-maintenance aesthetic boost and a consistent, colorful flame effect without changing their existing burner system. Also suitable for creative displays in aquariums or terrariums where inert decorative glass is desired—always follow appliance and aquarium-specific guidelines.
