You should note that your glass marble should not burn on its own; they are inflammable while adding some blaze to the flame.

Mixing Other Materials With Fire Glass

If fire glass is unavailable, you can use other logs and lava rocks. Lava rocks come in three different colors: Reddish-brown, black and gray. While they are alternatives, you should not mix them with fire glass, but they can be used as fillers.

Lava rocks limit the amount of heat they can tolerate; this means that they can pop while burning at a certain temperature. And since glass marbles can withstand high temperatures, lava rocks may not have that same capacity.

  3. For the last step, gently pour in your glass marbles.
