So I've been wanting to make a brick ovrn for a ehile now, but I have an unconventional idea. Would it be possible to build a double decker brick oven? Think of it this way, the lower deck would have the fire, the top deck would have the food. I'd assume that I'll need some openings (essentially vents) between them to maintain proper circulation/heat exchange. The decks will ne seperated by aa layer of bricks (the top layer of the bottom deck. Does this sound feasible?
