Lava Rock & Fillers

Here at Blazing Glass we have a variety of products that can be used as an accessory to our beautiful fire glass. They can even be used as stand alone fireplace and fire pit décor. These items include our fireplace lava rocks, silica sand, and volcanic ash.

We offer small, medium and large sized gas fireplace lava rocks to suit your specific needs. We recommend using our lava rock or fireplace silica sand or volcanic ash if you have a deep fireplace or fire pit, as a cheaper alternative to filling the whole space with fireplace glass. Simply put the lava rock, fire pit lava rocks, silica sand, or volcanic ash at the bottom to form the base and completely cover them with the fireplace glass so they are not visible. Gas fireplace lava rocks will also retain heat better than ceramic logs, making them more energy-efficient and thus saving you money.

The same above effect can be achieved with our fireplace silica sand or volcanic ash too. Silica sand color varieties will be available here at Blazing Glass very soon! Contact our Customer Service Center for questions.
