I have a gas firepit it my backyard. To get a more dispersed, even flame, I buried the burner in about six inches of sand and then some lava rock. The gas seeps through the sand which gives a more distributed flame as opposed to one big flame like you typically see in a gas firplace.

The point is, I do not think you need glass. Any type of material will work. I would guess that you could use red fishtank gravel if you wanted to.
