Fire glass is tempered glass manufactured as a medium to retain and direct heat in fireplaces and gas 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.

Manufacturing Process
A vast assortment of fire glass shapes, sizes and colors are available to match a wide variety of contemporary décors. During the manufacturing process, sheets of glass are tempered to withstand heat. This process prevents the glass from "popping" when used in a fire and negates the threat of sparking seen in traditional wood burning fireplaces or fire features. These tempered sheets of glass are then shattered and professionally tumbled to reduce the risk of injury from sharp edges. Although a variety of fire glass types exist, variations are purely aesthetic, and all varieties serve the same purpose within a fire feature.

Environmental Effects
Fire glass leaves no trace of ash, soot, grease or discernible odor when used as a medium. 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. Additionally, fire glass is often made from recycled glass, making for a "green" fire media option.
Fire Glass Care
Fire glass is designed to last a lifetime and requires very little care. The glass is designed to withstand years of use--indoor or outdoor--without breaking down or discoloring. Dirty fire glass can be cleaned using warm, soapy water to return its original luster. Since fire glass is not consumed during use, it does not need to be replaced.
Additional Uses
In addition to being used as a fire pit and fireplace media, fire glass is often used as a crafting item (e.g. in a wedding centerpiece).
