Reminiscent of the azure sky on a cloudless day, Celestial Tempered Fire Glass in Neptune Blue Reflective instantly turns a plain gas fire pit into something extraordinary. It's breathtaking to see the flames dance and jump across the illuminated glass.

A favorite for do-it-yourselfers, Celestial Fire Glass is no ordinary glass; it's made exclusively for use in fire pits and fireplaces. Its superior strength and durability ensure that it maintains its beauty throughout many, many fires. What's more, we use a special process to make our glass more reflective than other brands — so you get more shimmer for your money.

The Celestial difference:

  • Shine that won't quit. Most fireplace glass is tumbled. But we use a proprietary sifting process to remove small pieces with sharp edges without dulling the surface. Coupled with a mirror backing, this makes our glass the most brilliant available today.
  • Won't burn or fade in intense heat. Designed for fire pits, your colored glass has impressive staying power. It won't lose its rich shade or warp or melt.
  • Burns cleanly. Concerned about toxic odors? Celestial Fire Glass burns cleanly, so you can use it in your gas fire pit with complete peace of mind.
  • Premium packaging. Instead of a plastic bag, Celestial uses smarter packaging for its fire pit glass — a sturdy plastic jar with a carry handle.
  • A DIY must-have. Celestial fireplace glass also looks gorgeous in water features or as a filler for transparent vases. Mix colors and create stunning designs!
  • Free Expedited Shipping. All orders ship for free through U.S. Postal Service Priority Mail. You'll receive your order quickly and with no shipping costs to you.
