Koma, All sorts of questions since you’ve already done this…
Did you find your oven was adequate for one family? I’m guessing most people get a little over-ambitious about the size. “Why sure. You should be able to roast the whole fatted calf in there” 🙂
What did you use for a door? Sheet iron filled with vermiculite? Cast iron? A firebrick and clay block?
One brick thickness or two for the walls? Mortared arch or self-supporting for the vault? Dampered chimney?
You’re right about the stick-to-the-wall breads. Best just to have a dedicated tandoor for that. Until then take the blowtorch to the regular oven once a year.
