From Wikipedia, the free encyclopedia
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 to decrease risk of cuts. It is also available in other various shapes and sizes
