An easy way to change up the look in your gas fire pit table is to swap out the fire pit glass. Often called fire pit jewelry, the fire glass comes in a range of colors, shapes and reflectivity. Fire glass is as practical as it is pretty—filling the burner pan with fire glass covers the fire pit burner and drain holes to give the fire pit a finished look, and the fire glass helps disperse the flames.
Here’s a pro tip when deciding among the choices: Large glass chunks allow bigger flames while smaller glass pieces help spread the flame more evenly; and mirrored glass and reflective beads let the flames sparkle across their surfaces. Fire glass in gold, blue and red hues lend a rich glow and allow the flames to reflect off the many surfaces. Black fire glass creates a deep, dark backdrop that makes the flames the focal point.
Fire pit glass is made from tempered glass, so it won’t melt or release toxic fumes. It’s very different from decorative glass found in craft stores—do not substitute craft store glass for fire glass.
