What is fire glass used for?

Fire glass is primarily used as a decorative and functional media in gas fire pits and fireplaces. It safely conceals the metal burner ring, helps disperse the flowing gas to create a fuller flame, and effectively radiates heat without producing any smoke, soot, or toxic ash.

What is fire glass made of?

Fire glass is constructed from specially treated tempered glass that has been tumbled to remove sharp edges. This high-heat tempering process ensures the glass can withstand extreme, continuous temperatures without melting, cracking, or emitting harmful fumes when exposed to open flames.

How long does fire glass last?

Because it is engineered to handle extreme heat, high-quality fire glass lasts almost indefinitely. Unlike traditional wood or porous lava rock, it will not burn away, structurally degrade, or lose its vibrant coloration over time under normal operating conditions.

Does fire glass need to be replaced?

No, fire glass generally never needs to be replaced due to physical wear and tear. You only need to replace it if you decide to change the aesthetic or color scheme of your outdoor space. If your current glass begins to look dull or cloudy, it simply needs to be scooped out, washed with warm soapy water, and completely dried before being placed back into the pit.

Can you put fire glass in any fire pit?

No, fire glass should only be used in natural gas or liquid propane fire features. You must never place fire glass in a traditional wood-burning fire pit, as the extreme, uneven temperatures of a wood fire can cause the glass to dangerously pop, shatter, or melt.

Fire Glass

Fire glass turns a gas fire pit into a centerpiece that sparkles day and night. Our tempered fire glass is made to sit in the flame without melting, fading, or producing smoke, and it comes in reflective and classic finishes and a wide range of colors. Use it on its own, or layer it over lava rock to fill a deep burner pan.

Why Choose Fire Glass?

Fire glass is tempered glass that has been tumbled smooth and treated to handle direct flame. Unlike natural rock, it doesn't absorb moisture or break down over time, so it keeps its color and shape season after season. Because it reflects the light of the flame, fire glass gives your fire pit a bright, modern look, even when the fire is off.

Reflective vs. Classic Fire Glass

Reflective fire glass has a mirrored backing on one side that bounces the flame light outward, creating extra sparkle and a brighter glow. Classic, non-reflective fire glass has a softer look that lets the color of the glass stand out. Many people mix the two, using classic glass as the base and reflective glass on top for added shine.

How Much Fire Glass Do You Need?

Most gas burners need only about one to two inches of media over the burner to diffuse the gas and produce an even flame. To estimate, multiply the length and width of your burner pan by the depth you want, then use the coverage chart on the product page to convert that volume to pounds. For deep burner pans, fill the bottom with lava rock and use fire glass as the top layer to save on cost. Always follow your burner manufacturer's guidelines for media depth.

Mixing Fire Glass with Other Fire Media

Fire glass pairs well with fire balls and fire pit logs. Use a layer of fire glass as the base, then add ceramic fire balls for a modern look or fire pit logs for a blend of modern and rustic styles.

Caring for Your Fire Glass

Keep fire glass clean and dry for the best look and performance. Let the fire pit cool completely, then remove leaves and debris. To restore the shine, rinse the glass with water and let it dry fully before relighting. A metal burner cover or soft cover keeps rain and debris out between uses, and a glass wind guard helps prevent soot from building up on breezy nights.
