   Thanks for the information but it is much to expensive for my purpose.

   I think you'll have flaking and separation from the concrete
   pavers with any kind of stucco. Heat and water will wreak havoc eventually. If there is room dry lay some fire brick up the sides.

   Fire clay is simply added to regular mortar to enhance it's ability to move with heat cycles. It won't do anything by itself, and it won't help much in keeping a thin veneer of mortar on the surface of your masonry.

   That said, I see no reason you'd need to line your fire pit. Worst thing that'll happen is your pavers may crack a bit (less likely if they are reinforced), but so what? You'll never see it under the fire.

   PS: Did you make provisions for drainage? You don't want the pit to fill with water during a rain.

   Thanks for the input. I'm afraid that the pavers will crack and crumble over time; they aren't reinforced.

   I guess my only alternative is to use brick or line it with steel.

   Yes I do have drainage= 4 inches of 3/4 stone.

   So what if the pavers crack over time? It'll cost about $6 to replace them in a couple of years. Probably cheaper to replace periodically if needed than to prevent.

   You could put a layer of firebrick on the bottom, just laid lose. It's about $4 per square foot around here lately. You could do the bottom for about $25. I wouldn't worry about the walls.

   Just don't run a blast furnace in there and you'll be OK as-is.

   It's the top of the walls that will degrade the fastest.
   I agree that the money is enough to be of concern, but if you wanted
   to keep it whole the walls are the first place to protect.
