Fire Glass vs Lava Rock: What Goes in a Gas Fire Pit?

Key takeaways

  • Fire glass reflects flame and looks modern.
  • Lava rock gives a natural, earthy look.
  • Ceramic logs recreate a wood fire without the smoke.
  • Only use media rated for fire.

What the media does

The media covers the burner, spreads the flame and decides how the fire looks when lit and unlit. It also protects the burner from debris.

Fire glass

Tempered fire glass sparkles and reflects the flame, with colors from clear to cobalt, amber and copper. It suits modern designs and wipes clean easily.

Lava rock

Lava rock is dark, porous and natural, with an earthy look that suits rustic stone pits. It is inexpensive and good at spreading gas, though it can collect dust and debris.

Ceramic logs

Ceramic log sets give the look of a wood fire. They are popular in fireplaces and traditional pits where you want the glow without smoke.

Safety first

Never use river rock, regular glass or unrated stone in a gas fire. They can crack or pop. We supply the right media for your burner.

Quick answers

How much fire glass do I need?

It depends on the burner size and depth. We measure and supply the right amount so the burner is covered and the flame looks full.

Does fire glass get dirty?

It can pick up dust and soot over time. A rinse and a dry usually brings the sparkle back.
