Why Fire Pit Media Is the Upgrade Your Gas Fire Feature Needs

Instant Visual Transformation

Replacing basic outdoor fire pit rocks with reflective or colored fire glass shifts the entire character of a fire feature. Seven color options from cobalt to amber let you match your outdoor palette, and the reflective finish adds dimension that plain rock cannot replicate.

Better Radiant Heat Output

Tempered glass and lava rock both conduct and distribute heat from your burner, extending warmth toward your seating area. Choosing the right media type and depth ensures your fire feature performs as well as it looks.

Works With Any Gas Fire Feature

Every fire pit media option in this collection works with both propane and natural gas burners. From fire tables and fire bowls to indoor gas fireplaces, these media types are purpose-built for gas applications.

Built for Outdoor Conditions

Tempered fire glass is weather-rated and UV-stable. Lava rock is naturally porous and heat-resistant, proven through actual volcanic conditions. Both hold up across seasons without fading, cracking, or degrading.

Fire Pit Media Ideas for Every Outdoor Fire Feature Setup

Modern Fire Tables

Sleek concrete fire tables look their best filled with reflective or colored fire glass. The glass catches ambient light during the day and amplifies the flame at night, turning the table into a focal point.

Rustic Fire Bowls

Carbon steel and raw concrete fire bowls pair naturally with crushed lava rock. The earthy black and gray tones reinforce the natural aesthetic, and the porous texture sits comfortably in heavier bowl materials.

Indoor Gas Fireplaces

Ceramic stone media from American Fyre Design is purpose-built for indoor use. The stones look like natural river rock, produce no soot, and stay clean through extended use in living rooms and great rooms.

Poolside Fire Features

High-end pool fire bowls benefit from reflective fire glass that picks up the water surface and amplifies visual impact after dark. The glass handles moisture without degrading, making it a natural fit for poolside installations.

Fire Pit Media FAQs: Glass, Lava Rock and Ceramic Stones

How much fire pit media do I need to fill my fire pit?

About 1 lb of 1/4" fire glass per 100 sq. in. of burner surface at a 1" fill depth. A 40 lb bag of lava rock covers most standard fire pits at the recommended level.

What is the difference between fire glass and lava rocks for fire pits?

Fire glass is tempered, tumbled glass designed for color and reflective visual impact. Lava rock is natural volcanic material offering earthy texture and strong heat distribution. Both are gas-compatible: the choice comes down to aesthetic preference and budget.

Can you use lava rock and fire glass together in the same fire pit?

Yes. Layering is common: a base of 3/4" lava rock for airflow and heat, topped with 1/4" fire glass for the visual finish. It is a cost-effective way to get the look of glass without filling the entire pan.

Is fire pit glass compatible with both propane and natural gas?

Yes. All tempered fire glass and lava rock sold by Fire Pit Surplus is compatible with both propane and natural gas burners. Verify your burner manufacturer's recommended media depth for your specific setup.

How do I clean and maintain fire pit media?

Rinse fire glass with water and let it air dry fully before returning it to the burner. For lava rock, soak in water to loosen debris, rinse, and dry. Avoid soap on lava rock as it can absorb residue into the porous surface.
