I built one with just clay and straw, used it every weekend for years, it cracked, rebuilt it, used for another two years, cracked again, rebuilt it a third time. I've moved to a new house and already miss it. Even if I'm not making pizza, it's great just for an outdoor fire while sitting in the hammock. It's contained and uses like 1/4 of the wood while not being as dangerous.
A great way to spend a weekend afternoon is to fire it up and loaf on the hammock. I'd also use it to bake bread, make peach cobblers in cast iron, and smoke bacon. Great times. Maybe I could get the parts to rebuild it this weekend...
