The American Fire Glass 1/4-in Classic Fire Glass perfectly compliments both indoor and outdoor fire features, bringing a classy appeal to every gathering. Made of 1/4-in thick color-infused tempered glass, this non-reflective fire glass is a practical alternative to ceramic and stone. Covering the entire floor of a fire feature, it effectively hides pipes and tubes often visible in gas fireplaces or fire pits; making fire glass a more desirable alternative to the more common ceramic logs and fire stones. Designed to withstand harsh weather and temperatures of up to 1300 degrees Fahrenheit without ever cracking, or losing its color or shape, used correctly, it could last a lifetime! Also, it does not emit any toxic fumes, smoke, or ash, and is easy to clean and maintain.
