Ok, so you’ve seen sand in the bottom of a Fire Pit and wondered…….but why?
Well you’ve come to the right place! Here we are going to explain why sand is used so that you can decide if it applies to your Fire Pit.
We are referring mainly to wood and charcoal fired Metal Cast Iron fire pits that come in all shapes and sizes but more commonly a bowl. Sand is not required in a propane or natural gas fire pit.

What type of Sand for a Fire Pit?
We recommend Silica Sand, the type you find in construction or when you’re having a bad day on the golf course and land your ball in the bunker!
Non Silica Sand often contains more impurities which makes it more chemically reactive. It is usually darker in color however shades of white, pink, green and black can be found depending on where its originated from.
If you decide to use sand in your fire pit you must avoid getting it wet while the fire pit is not being used, wet sand causes the metal to corrode. For this reason most people avoid using sand and the hassle of keeping it clean.
