The wife and I tend to have large fire so I had to get a heavy duty fire ring. The ring you see there is 3/4" Ductile Iron pipe which is 60" round, and this was a cut off from a water main project in Naperville, IL. I'm not sure what got this fire going so big, but most of mine start out this way so that I can get enough heat to burn the larger 8-10 inch logs.
Nice catch on the images I will have to show my wife that tonight.
