GRISUN Fire Glass 1/2-inch 20 lb Bahama Blend - Aqua/Teal Reflective, Heat-Resistant

GRISUN 20 lbs Bahama Blend 1/2-inch fire glass is tempered decorative glass designed for gas or electric fire pits and fireplaces to produce gleaming, heat-retaining accents without melting or fading.

Brightly colored and uniformly tumbled, this Bahama Blend fire glass offers vibrant aqua, teal and clear tones that reflect flames and light. Each 20-pound bag contains half-inch pieces that work with propane, natural gas and electric fireplace systems, and they can also top lava rock in outdoor fire pits or line indoor glass fireplaces. The pieces are tempered for heat resistance and corrosion stability so they keep their color and sparkle over repeated use.

How does GRISUN fire glass behave with different fuel types?

The glass is non-combustible and compatible with propane, natural gas and electric fires. It won’t burn or emit odors when heated; instead, it reflects and disperses light to boost flame appearance while retaining heat without degrading.

• Safe for gas and electric fireplace systems when installed per manufacturer guidelines.
• Doesn’t melt or deform under normal fireplace temperatures.
• Minimal dust or residue compared with untreated stones.
• Works well over a layer of lava rock to protect burners.

Will the Bahama Blend colors fade or crack over time?

These pieces are tempered and color-stable, formulated to resist fading from heat and UV exposure in outdoor settings. Proper installation and avoiding direct flame impingement will keep the finish bright for many seasons.

• Heat-resistant tempering reduces fracture and discoloration risk.
• Fade-resistant pigments maintain color outdoors.
• Regular rinsing removes ash or soot without harming finish.

How much coverage does a 20-pound bag provide and how should I layer it?

A 20-lb bag of half-inch fire glass covers roughly 1 to 1.5 square feet at a 1–2 inch depth, depending on layout. For best results, lay a base of lava rock or fire-rated sand to support burners, then spread glass in an even layer to the recommended depth for your appliance.

• Estimate coverage: about 1–1.5 sq ft at 1–2 in depth per 20 lbs.
• Use lava rock as a protective base for gas burner ports.
• Avoid mounding directly over burner openings; follow your fire appliance instructions.

How do I clean and maintain GRISUN fire glass?

Cleaning is straightforward: cool completely, then remove and rinse or use a gentle scrub to remove soot. Because the glass doesn’t absorb liquids, it doesn’t stain easily; store unused glass indoors to prevent grime build-up.

• Allow glass to cool fully before handling.
• Rinse with water or scrub lightly for soot removal.
• Replace any fractured pieces; discard dust and small debris.

Who is this for: GRISUN Bahama Blend 1/2-inch fire glass is ideal for homeowners and designers who want a low-maintenance, decorative solution to improve their fireplace or fire pit visuals. Choose it if you want durable, heat-safe glass pieces that enhance flame color and offer an upscale look for patios, terraces, poolside fire features, indoor glass fireplaces, and modern fire tables.
