However, the reflection of the fire glass allows it to absorb more heat and hence emit more heat.

Furthermore, fireplace rocks are typically available in smaller, more uniform pieces. This enables them to distribute heat more uniformly, making the surrounding environment seem warmer.

What is Lava Rock?

Lava rocks are igneous rocks that form spontaneously as a result of volcanic activity. They are commonly found around volcanoes as magma heats up and cools down through the emission of gas.

This, in turn, generates a response on the surface in the form of uneven rock forms known as basalt. Lava rocks are highly porous because they came from naturally high temperatures.

As a result, they are excellent heat conductors and a popular option for fire pits since they diffuse heat equally as well.

What is Fire Glass?
