Skyflame 15LB 1/2" Cobalt Blue fire glass is tempered decorative glass designed to replace lava rock in propane fire pits and fireplaces, giving flames a vibrant blue shimmer while resisting heat and discoloration.

Upgrade your outdoor or indoor fire feature with a bright, reflective medium that elevates flame color and appearance without affecting burner performance. These half-inch cobalt blue pieces are tempered to tolerate repeated heating cycles and are sized to sit cleanly around gas flames, producing a consistent sparkle and depth of color that draws the eye.

How will this fire glass change the look of my propane fire pit?

Replacing standard media with Skyflame cobalt blue fire glass reframes the visual focal point of any burner. The tempered glass reflects light and creates a jewel-like surface that makes flames appear richer and more three-dimensional.

• Enhances flame contrast and color pop against blue glass
• Creates a mirror-like shimmer under flickering flames
• Uniform 1/2" pieces deliver an even surface and consistent glow

Is this fire glass safe for propane burners and long-term use?

Yes—Skyflame fire glass is tempered and formulated for high temperatures common to gas burners. It will not melt or significantly fade under normal use, but should be maintained according to safety guidance to ensure longevity.

• Tempered to resist cracking from heat cycles
• Non-combustible glass; suitable for propane and natural gas systems
• Requires routine cleaning to prevent soot buildup and ensure airflow

How do I install and care for the 15LB cobalt blue pieces?

Installation is straightforward: layer the fire glass over your burner per manufacturer spacing recommendations and avoid covering the burner ports. For cleaning, simple rinsing and gentle vinegar solution restores shine; always dry pieces fully before reuse.

• Pour evenly to recommended depth—check your fireplace or pit manual
• Clean with water and mild vinegar; dry completely to prevent steam hazards
• Wear gloves when handling to protect hands and keep glass pristine

Will the color stay vibrant over time?

Skyflame’s cobalt finish is formulated to retain its hue under typical gas fire use. While soot and dust can dull the surface, routine cleaning will restore the original luster without color loss when used properly.

• Tempered glass resists discoloration and fading
• Dust and soot are removable with gentle cleaning
• Avoid abrasive cleaners that could scratch the surface
