American Fire Glass AFF-COP12-10-J 1/2" Copper Fire Glass 10lb Jar. Copper has been prized for thousands of years and is still one of the most important materials on Earth. It has a naturally lustrous and luxurious look to it which brings a touch of style and warmth to everything it adorns. If your customers want to bring their drab old fireplace back to life, we offer copper fire glass from our 1/2 inch fire glass collection. As lovely as the copper fire glass from our 1/4 inch collection, this 1/2 inch glass is clearly chunkier, allowing for better air circulation and delivering a bigger and more impressive flame. Our 1/2" copper fire glass works well in both indoor fireplaces and outdoor fire pits. It easily blends with a wide variety of color schemes and adds a touch of sophistication to its surroundings. The large, dancing flames rising from the bed of copper fire glass provide a fire experience that will leave onlookers mesmerized.
