GASPRO Fire Glass for Propane Fire Pit, 20 lb 1/2" Reflective Cobalt & Platinum Blend, Tempered Non-Combustible

GASPRO 20 lbs 1/2-inch reflective fire glass is a decorative, non-combustible replacement for lava rock that improves heat radiation and creates a sparkling blue-and-platinum flame display for propane fire pits and tables.

Replace dull lava rock with a cleaner, more visually striking surface: this 20-pound bag contains half-inch tempered glass pieces in cobalt blue, Caribbean blue and platinum finishes that reflect flame and daylight for a shimmering effect. Designed for propane fire pits and fire pit tables, the tempered glass resists melting, popping, ash and smoke while concealing burner components for a polished look.

How will GASPRO fire glass change the look of my fire pit?

The mirrored surfaces and mixed blue-platinum palette create a multicolored glow by day and an intensified, gem-like flame at night. Instead of dull black lava rock, the reflective pieces catch and scatter light so flames appear brighter and more decorative.

• Half-inch pieces create consistent, glittering coverage across the burner area.
• Mixed cobalt, Caribbean and platinum tones give depth and color variation.
• Reflective finish amplifies ambient and flame light for a dramatic presentation.

Is this fire glass safe and compatible with propane fire pits?

GASPRO fire glass is tempered to withstand high temperatures without melting or producing smoke, ash or popping typical of untreated materials. It’s intended for decorative use with gas burners; always confirm your pit design and burner compatibility before installing.

• Tempered glass resists degradation from heat and handles typical fire pit temperatures.
• Does not produce ash or measurable smoke when used with propane burners.
• Use only with gas-fired pits; verify whether your pit requires additional lava rock or media.

How much glass do I need and how do I install or maintain it?

A 20-pound bag covers most small to medium fire pit bowls when spread evenly as a single layer; deeper coverage or decorative piles will require more material. Installation is simple: clean and dry the pit, cover exposed burner elements as recommended by the manufacturer, then distribute the glass evenly. Maintenance is minimal—periodic rinsing and drying keeps the pieces bright.

• 20 lbs suits small-to-medium sized pits; measure bowl area for precise coverage estimates.
• Clean and fully dry glass before initial use to prevent trapped moisture from sputtering.
• Occasional rinsing with water and air drying preserves shine; avoid harsh chemicals.

What visual and practical benefits should I expect compared with lava rock?

Compared to lava rock, GASPRO reflective fire glass offers greater light reflection, a cleaner appearance, and less routine cleanup. The smooth, tempered pieces hide plumbing lines and burner hardware while providing a jewel-like aesthetic that elevates outdoor living spaces.

• Cleaner burning surface—no ash or soot buildup from the glass itself.
• Hides unsightly burner components for a finished look in fire tables.
• Durable finish maintains color and sparkle under regular use.

Who is this for? GASPRO 20 lbs 1/2-inch reflective fire glass is ideal for homeowners and designers who want a low-maintenance, visually striking upgrade for propane fire pits and tables. It’s a good choice for people replacing lava rock, staging outdoor spaces for entertaining, or anyone seeking a colorful, reflective media that conceals burner hardware while enhancing flame appearance. Always check your fire pit’s manual to ensure glass media is compatible and follow safety guidance for installation and drying before first use.
