Fire glass is tempered glass manufactured in pebble-sized fragments used as a medium to retain and direct heat, usually in gas fireplaces and 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 usually comes in small shards with rounded edges to decrease risk of cuts.
