Celestial Fire Glass starts with a high-quality tempered glass and finishes it with a special sifting process to ensure optimum sparkle. We never tumble our glass as other makers do because it dulls the surface, reducing the shine.And because we use a good quality glass, our fire glass products withstand high temperatures without losing their color and radiance. Nor do they release toxic chemicals or smells into the air.After going to all the trouble to create the highest quality fire glass, we want to make sure it gets to you still looking fabulous. So, we package our glass in 10-pound jars to make it easy to lift. We even added handles to make the jars easier to carry. We add two more layers of protection before sending it on its way.Neptune Blue Reflective is a clear, fresh blue that puts you in the mind of a brilliant summer sky or the twinkling waters of a tropical watering hole. Either way, it will look amazing in your fire pit or fire table. Mix it with Meridian Blue and Europa Blue to create an ocean of color.In addition to fire pits, Celestial fire glass is safe to use in indoor fire features or centerpieces. Sprinkle it in your water feature or use it in hardscapes. You imagination is the limit.
