Cost: Fire glass is generally more expensive than other fire media options, which may be a concern for those on a tight budget. Heat retention: Fire glass does not retain heat as well as lava rocks, which could be a consideration for those seeking maximum warmth from their fire table.

Using sand or Exotic Glass Base Filler. These options are both safe to use with the fire glass. There are fillers that are not safe to use under fire glass. Fillers like lava pebbles, lava rocks, general landscaping rocks, and porous materials should not be used under fire glass.

Fire glass gives off more heat than wood, or fake logs combined. Not only is gas cheaper than burning wood, but adding the extra heat given off by the glass ensures you get more bang for your buck!

We recommend using sand or pea gravel (fine) to achieve this result. DO NOT use lava rock, lava pebbles, rocks/pebbles or any other porous material UNDER the fire glass as natural gas or propane (LPG) may sink between the gaps, becoming trapped and potentially causing hot glass to pop or jump from your fire pit.

Give the glass a final rinse using clean water (a garden hose makes it easy). Particularly if you're using the tempered variety, it's a good idea to dry your glass completely prior to using it again.

Even though fire glass doesn't burn, it does retain heat and refract light from the flame. Because fire glass crystals do radiate heat, they serve a dual purpose: keeping things warm and looking great while doing it.

Lava rocks are a great resource for landscaping use – they have a long life, don't blow away, keep weeds and bugs away, retain moisture, and look great.

Fire Pit Safety

If burning wood, place a layer of lava rock at least 4-5 inches deep. Then place your firewood on the lava rock. For gas fires, fill the fire pit with enough lava rock to at least cover the fire ring. Do not use rock or gravel of any kind in place of lava rock; it can potentially explode when heated.
