Cosmic Copper Reflective Tempered Fire Glass by Celestial Fire Glass lends a warm, earthy sparkle to your outdoor gas fire pit or fireplace. You'll love the way it glimmers and twinkles in the light, even when the fire is out!

Why is Celestial Fire Glass better than other brands? Our product is designed to retain its beauty in extremely high temps. Plus, we manufacture our fire glass to be ultra-reflective, so that it delivers maximum visual impact. Put on your DIY hat and turn your fire pit into the eye-catching focal point of your backyard deck or patio.

The Celestial difference:

  • Unique reflective finish. Rather than tumbling it, which dulls the glass surface, we remove small pieces with sharp edges with a gentle sifting process — and add a reflective backing.
  • Worry-free burning. Enjoy peace of mind knowing that your fire pit glass won't melt and give off toxic fumes.
  • Heat-resistant glass. Your premium fire glass won't crack or explode while burning, nor will it fade or become discolored over time.
  • An all-purpose decorative accent. Not just for fire pits. This fire glass is a do-it-yourself must-have that can be poured into vases or used to lend sparkle to water features.
  • Better packaging. We've put our fire glass into a sturdy plastic jar instead of a bag. This makes it much easier to transport, pour, and store.
