OnlyFire 10 lbs Fire Glass Rocks 1/4 Inch - Cobalt Blue Reflective Tempered Glass for Fire Pits

Elevate your outdoor flame space with OnlyFire fire glass rocks

Transform a standard burner into a striking centerpiece with 1/4 inch high-luster fire glass. The cobalt blue option delivers a jewel-like glow as flames dance across the reflective surface, creating depth and color that catches the eye from across the patio. Unlike traditional lava rocks, these glass rocks sparkle under sunlight and glow warmly after dark, making your fire pit or fireplace feel like a featured element of your outdoor design.

Each 10 pound bag is portioned for standard fire pits and fire tables, offering a clean, simple setup. The glass is designed to stay vibrant through seasons of sun and shade, giving you consistent color without fading. This product is part of a broader color spectrum, including exclusive mixes like Aqua Blue and Platinum, plus solid options such as Cobalt Blue and Onyx Black, so you can curate a cohesive look across your outdoor space.

Safety and performance are built in. The glass is industrial-grade tempered to endure high heat up to 1300°F without melting, cracking, or releasing smoke or odors. It is suitable for both propane and natural gas installations, presenting a durable, eco-friendly alternative to wood or traditional lava rock, and designed with family safety in mind.

Installation is straightforward. Just pour the glass onto the burner and keep the burner holes clear. Maintenance is simple too—rinse with a vinegar and water solution to restore its factory shine. Beyond fire pits, this glass doubles as a decorative accent for indoor planters, Zen gardens, walkways, fish tanks, and vases, thanks to its non-toxic, UV-resistant properties that keep color vibrant over time.
