PLEASE NOTEUnless otherwise stated, fire glass can be used with natural gas burning features ONLY & colors may differ slightly than what is shown online. Fireside Expressions is adamant about this for the safety of our valued customers. Some manufacturers offer specialty components (such as ventilation collars) that make the combination of propane and fire glass compatible. However, this is only offered with limited products.

  • 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 can lead to the 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 and our ceramic river rocks allow propane to dissipate and is the safest choice for your gas feature. (In addition, it is always a good idea to incorporate lava rock into the bottom portion of natural gas burning features. This helps with gas dispersion and allows you an affordable way to fill your fire pit or bowl.)  ​
  • Due to the tumbling process, glass will gather dust and need to be rinsed prior to use.

As always, our team of experts is available at 1-888-986-1535 to help answer your questions!

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.
