My oven is always much colder at the bottom than the top, and I've had issues cooking pretty much everything because of it. According to the gas guy there is nothing wrong with it, so I'm just trying to find ways to work around it.
So far I've tried putting a stoneware baking dish full of water on the bottom of the oven, and a big cast iron griddle. Neither have seemed to help much. I know there has been a lot of discussion about using unglazed tiles or a pizza stone in a gas oven to help keep the heat even. I have been unable to find the right tiles or a pizza stone that is small enough to fit in my tiny oven at a price that I can afford. So I am wondering about possible alternatives. Namely, ordinary house bricks, which I happen to have a stack of in the garden. I'm not interested in baking anything directly on them.
Would normal bricks contain harmful junk that would off-gas in an oven? Would wrapping them in foil mitigate this enough to make them safe? Would this idea even work at all?
