Fire Glass

Create a shimmering "fire and ice" display with our American-made fire glass! This is a stunning alternative to traditional log sets in your fire feature. The cut and texture of each individual tempered fire pit glass piece directs the natural fluidity of the flame as it graces the prisms below. Your fire feature will go beyond the definition of beauty when you embellish it with your choice of colored glass. We have a vast collection of  1/4" or 1/2" options, as well as reflective fire glass available in a large assortment of colors for infinite custom appearances. 

It can be tricky to figure out how much fire glass is appropriate for use in your fire pit or fire bowl. For help with this matter, check out our handy glass calculator below! 

PLEASE NOTE: Unless otherwise stated, fire glass can be used with natural gas burning features ONLY & colors may differ slightly than what is shown online. 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 your gas feature. (In addition, it is always a good idea to incorporate lava rock into the bottom portion of natural gas burning features.) Fireplace Doors Online 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.

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.
 

FAQs

Do I need to clean my fire glass?

  • There is no maintenance required. Your fire glass will be free of soot and odors. It will not leave any residue in the bottom of your fire bowl.
    • It is, however, very possible for your gas burner to leave behind a residue of soot if fuel connections were not installed properly (wrong air mixer, malfunctioning gas regulator ect). In that case, you can scoop out small amounts of glass at a time and wash them in a strainer with warm water and a small amount of mild soap. Allow your fire glass to dry completely before replacing.

Are there any sharp piece of fire glass that might cut me?

  • There is always the possibility of small pieces of glass nicking your hands and fingers. For this reason, we do recommend the use of work gloves when handling fire glass. However, please know that we take every precaution necessary to eliminate this issue to the best of our ability. Our fire glass is tumbled many times to round off the edges and smooth the surface of these pieces.
    • REMEMBER: do not touch fire glass while it is still hot!

What is reflective glass?

  • This type of colored fire glass has a reflective finish on one side. This concept is similar to the reflective backing of a mirror. Adding this element to fire glass allows the media to bounce light off its prismatic surfaces for a shimmery display of sparkle and glitz!
