onlyfire Fire Glass Rocks 1/2-inch 10 lb — Tempered Fire Pit & Fireplace Glass, Heat-Resistant, Low-Maintenance

Onlyfire 10 lb 1/2" fire glass is tempered, jewel-like glass media designed to replace lava rock in propane and natural gas fire pits, delivering brilliant color, heat resistance, and low maintenance.

Upgrade a fire pit or fireplace into a cleaner, more decorative focal point with these half-inch fire glass beads. Each 10-pound bag contains uniformly sized, tempered glass pieces that reflect flame and sunlight while offering a durable, non-combustible surface for gas burners. The material is engineered to resist heat, minimize soot and odors, and keep its color over time—making it a practical and attractive alternative to traditional stone or lava rock.

How does this fire glass perform around high heat?

Onlyfire glass is tempered to tolerate the temperatures commonly produced by propane and natural gas burners. The manufacturing process strengthens each bead so it won’t melt or fracture easily under normal fireplace or fire pit conditions. This means long-term stability and less replacement over time compared with non-tempered decorative glass.

• Tempered to withstand extreme temperatures up to 1300°F.
• Non-combustible, producing no smoke, soot, or toxic fumes.
• Uniform size helps maintain even flame patterns and consistent airflow.

Will these glass rocks be hard to install or clean?

Installation is straightforward: pour the glass over your burner and leave burner ports clear for proper gas flow. Maintenance is minimal—periodic rinsing with a mild vinegar-and-water solution restores shine and removes grime. Because the pieces are non-porous and UV-stable, they resist staining and fading, so upkeep remains simple.

• Pour-and-position installation—no special tools required.
• Easy cleaning with a vinegar and water rinse.
• 10 lb bag size suited for many standard fire pits and tables.

What color and style options are available, and how do they look with flames?

Onlyfire offers single-color options like Onyx Black, Cobalt Blue, and Plutinum, as well as pre-mixed designer blends that combine tones for a layered, dynamic appearance. The high-luster finish maximizes reflectivity so flames appear brighter and more jewel-like, producing a dramatic visual effect both day and night. Choose a single shade for a sleek, modern look or a mix for a richer, textured appearance.

• Single-color choices for consistent, modern aesthetics.
• Pre-mixed blends for multi-tonal sparkle and depth.
• High-luster surface enhances flame reflectivity and visual impact.

Can I use these glass beads for projects other than fire pits?

Yes—these glass beads are versatile decorative media suitable for indoor and outdoor uses beyond gas burners. Their non-toxic, colorfast properties make them a stylish option for planters, tabletop bowls, walkways, water features, and aquarium accents. They retain their color and finish when exposed to sunlight or submerged, giving you many creative possibilities.

• Safe for decorative displays, planters, and vases.
• Suitable for water features and aquariums (non-toxic, colorfast).
• Durable outdoor use: UV-resistant and non-fading.
