Does your next do-it-yourself project involve giving your fire pit a sophisticated overhaul? Add eye-catching color and brilliant shine with Dark Matter Black Reflective Tempered Fire Glass by Celestial Fire Glass. This deep shade looks distinctive in any style fireplace or fire pit, and provides a striking contrast with the flames.

While most brands tumble their fire glass to remove sharp edges, resulting in a duller surface, we use a special sifting process to remove small sharp shards of glass that retains a smooth surface. As a result, our fire pit glass delivers incomparable radiance. You'll love the way it comes to lustrous life when the fire is ablaze!

The Celestial difference:

  • Durable and lasting. Your tempered fire glass is engineered to provide superior strength. It won't melt, crack, or explode as cheap brands do.
  • Dazzling shine. Our glass features an extra-smooth surface that reflects the light better than tumbled glass. Your DIY efforts will result in intense luster!
  • Burns cleanly. Thanks to its superior strength and quality, Celestial Fire Glass does not release toxic, smelly odors into the air while burning.
  • Not just for fire pits. Create stunning centerpieces with glass bowls or vases, or scatter your fire pit glass in a water feature as a shimmering accent.
  • Comes in a jar, not a messy bag. Your glass comes in a user-friendly plastic jar with a carrying handle on top. No bags that tear and spill.
  • Free Shipping. All orders ship free via USPS Priority Mail. Receive your fire glass in 3 days or sooner!
