How hard is it to add bricks to an oven? We just purchased our second location, which has deck ovens. They work fine except for one problem, no bricks/stones! So if we get busy, everything cooks slower and slower. They lose heat so quickly. Taste wise, “Bricking” the pizza on the metal just doesn’t have the same effect. This may be a stupid question, but how would I go about finding replacement stones? Would it be easier or cheaper to just find new ovens?
