What is Fire Glass and How Does it Work?

Fire glass is composed of small bits of tempered glass that is used in fireplaces and fire pits. The fire and ice combination quickly became a fast growing trend for homeowners and designers since its introduction in the mid 2000’s. Since then, it has been much more common to see fire glass used in fire pits, tabletop fireplaces, and fireplaces.

Fire glass serves two purposes; aesthetics and functional. Fire glass became a popular alternative to fake ceramic gas logs that kill the natural ambiance of a dancing flame. Exposed gas lines create an awkward visual that makes it apparent that you are not experiencing a real flame.

Fire glass provides a decorative way to cover up gas jets with beautiful pebbles and crystals that not only look great but increase heat radiation by up to 4 times! Fire glass pebbles are available in a variety of shapes and colors that can create a glowing focal point in your backyard or inside the family room.
