PLEASE NOTE: Fire glass can be used with natural gas burning features ONLY. Fireside Expressions is adamant about this for the safety of our valued customers. 

  • Because propane is heavier than natural gas, it will sink to the bottom of your feature. Small pieces of fire glass will not allow propane to circulate, and this could can lead to explosion of this particular media. Even with larger fire glass pieces, there is still not enough room for the gas to dissipate from wind and other factors. Lava rock allows propane to dissipate and is the safest choice for propane features. (In addition, it is always a good idea to incorporate lava rock into the bottom portion of natural gas burning features.)

We recommend covering the burner with a layer of cinders/lava rock. These should be 1" diameter or larger. Glass should then be used as a topping over cinders/lava rock to approximately 2” in depth. This helps save material, money, and allows for safer operation.
