Buying Guide
What size should you choose?
- Smaller beads (1/2 inch) offer a dense, shimmering look and are great for medium pits. They spread flame color evenly and reduce the risk of creating uneven flame pockets.
- Larger pieces (1 inch) provide a bolder, more dramatic display and are ideal for wide pits or tables where pieces are more visible.
Which color and finish matter?
- Caribbean Blue with a reflective finish adds daytime sparkle and nighttime glow, balancing heat reflection with visual appeal.
- Beads versus cubes: Beads offer uniform surface and smooth spread; cubes can create facets of color that stand out from different angles.
Durability and safety considerations
- All listed products are designed for high-heat environments and outdoor use. Look for tempered glass for enhanced durability and longevity.
- Handle with gloves during installation to avoid cuts from sharp edges. Regularly inspect for chips or cracks and replace as needed.
Compatibility and maintenance tips
- Most Caribbean blue fire glass is suitable for propane and natural gas installations. Confirm your specific pit model supports glass rock fuel types before replacing lava rocks.
- Keep glass clean by brushing off dust and debris. Avoid pouring liquids directly onto glass to minimize soot buildup.
