Celestial Tempered Fire Glass in Cosmic Copper Reflective lends an earthy sparkle to your fireplace or fire pit. It's the perfect decorative accent in the fall months, or all year round. You'll love how this warm, rich tone is set off by the fiery flames.

When it comes to luster, no other brand outperforms Celestial fire pit glass. Never tumbled in a machine, our glass has an extra-smooth surface to maximize light reflection. We've also added a mirror coating to pump up the brilliance even further. Who ever thought your outdoor fire pit could be such a do-it-yourself showpiece?

The Celestial difference:

  • Unstoppable sparkle. While most fire glass is tumbled to remove sharp edges, we use a special process to maintain a smooth surface. Combined with a mirrored coating, this makes Celestial fire pit glass uniquely shiny.
  • Retains its beauty. This fireplace glass is made extra-strong to stand up to extreme temps. It won't discolor, fade, or melt like sub-bar brands.
  • No chemical smell. Worried about toxic fumes? Celestial Fire Glass won't produce noxious odors, so you can feel good using it around family and friends.
  • The perfect DIY accent. Use our tempered glass to fill up tall vases with shimmering color or toss a handful in a fountain or other water feature.
  • Premium packaging. Plastic bags can tear and spill. Luckily, Celestial packages its fire glass in sturdy plastic jars with a convenient carry handle.
  • Free Priority Mail Shipping. All orders ship for free through USPS Priority Mail. We ensure you'll receive your fire glass quickly by using Priority Mail for all shipments.
