Fire glass

Fire glass is tempered glass manufactured in various shapes and sizes and is used as a medium to retain and direct heat, usually in natural gas fireplaces and natural gas or propane fire pits. Fire glass does not burn, but retains heat and refracts light as a result of burning gas. Fire glass (like artificial logs and stones) is additionally used to obscure the gas plumbing inherent in gas fireplaces or stoves.

Fire glass comes in quarter inch and half inch shards of tempered glass with smoothed edges that have been professionally tumbled to decrease the risk of injury. Because the glass is tempered beforehand, it runs no risk of "popping" and does not throw sparks the way traditional wood burning fireplaces and pits do. It is also available in other various shapes and sizes.^{[1][2][3][4][5][6]}

Fire glass does not leave traces of ash, soot, grease, or any discernible odor behind compared to wood or coal. Additionally, flames produced using natural gas do not produce any smoke, produce less toxic gases, and leave no trace of residual pollutants such as tar within the home. The combination is considered an eco-friendly burning solution. Fire glass works best indoors although can be dangerous.^[7]
