Cobalt Blue Reflective Fire Glass 1/2” 25LB (FG-COBALTBLUE-RF-25)
Tempered, reflective fire glass in deep cobalt blue. The mirror coating catches and amplifies flame, giving fire pits and fire bowls a striking jewel-toned glow at night. 1/2" size, 25 lb bucket — covers approximately 30–40 lbs needed for a standard 24" round fire bowl.
Reflective fire glass is regular fire glass with a mirrored coating fused to one side of each piece. That mirror finish doesn’t just sparkle — it actively reflects firelight, making the flames look fuller, brighter, and more dynamic than they would over standard fire glass or lava rock.
Cobalt blue is the deepest, richest blue in the spectrum. Against orange flame, it creates a contrast you don’t get from any other color — saturated, jewel-toned, and unmistakable from across a backyard.

Why fire glass over lava rock
Lava rock degrades. After a season or two it crumbles, leaves dust on your patio, and loses its color. Tempered fire glass holds up indefinitely, doesn’t soak up rainwater the way lava rock does, and gives a far more refined look — closer to the fire features you see at high-end resorts than a campfire.
