The center of the fire pit can be covered with several inches of Blue Granite, Mason Sand or Lava Rock. Never use limestone as excess heat can cause limestone to explode.
What kind of stone do you use for a fire pit?
Hard rocks like granite, marble, or slate are much denser, and therefore less likely to absorb water and explode when exposed to heat. Other rocks that are safe to use around and in your fire pit include fire-rate brick, lava glass, lava rocks, and poured concrete.
Do you need special stones for a fire pit?
Flagstone is an ideal material for the fire pit cap. No part of the fire pit should be made with flammable materials (e.g., plywood shipping pallets) or non-porous materials that hold water, such as pea gravel, river rocks, or compressed concrete blocks; these materials can trap steam and eventually explode.
