HOW MUCH YOU NEED?

Round Fire Pit

Diameter (A) x Diameter(A) x Glass Depth (B) / 24 = Glass (lbs.)

We recommend a minimum 2” of fire glass depth for most installations. For example, a 24" diameter fire pit at the recommended 2” of fire glass depth: 24 X 24 X 2 / 24 = 48 lbs.

Rectangular Fire Pit

Width (A) x Fireplace Depth (B) x Glass Depth (C) / 19 = Glass (lbs.)

We recommend a minimum 2” of fire glass depth for most installations. For example, a 30" X 10" fire pit at the recommended 2” of fire glass depth: 30 X 10 X 2 / 19 = 31 lbs.

Square Fire Pit

Width (A) x Width (A) x Glass Depth (B) / 19 = Glass (lbs.)

Indoor Fireplace

If you order these, make sure nothing else is shipped with them in the same package. It will totally smush the other item(s). Black soot comes out, or it did with my order. Understand that these are lava rocks, so I am not complaining. Just rinse them off with water and let them dry before you put them in your babies house. PERFECT!

The installer dump a bag of small lava rocks but it did not cover the whole space. These rocks are bigger and I just mixed them up with what was already there. They provide a nice finish touch.Ps. Be careful to keep them from your gas embers and gas flames.
