I have big pcs of flagstone in my yard and I wanted to use it to make a firepit, can flagstone withstand heat?
My goal was to dig a hole and lay a couple of the larger stones on the bottom, grade up the sides and cover them with smaller stones, then make a few layers of the flagstone at the top. I heard that some stones can explode (ie. sandstone). PS. I am time challenged right now and in a pinch for a firepit so this is just a temporary fix, since I have a bunch of flagstone laying around, I thought I would put it to use and I would solve the fire dilemma. I just do not want to explode!!!
