I recently purchased a 3/4", 17" X 21" hot rolled steel plate and would like to raise it in my oven so that it is closer to the broiler coil (my oven rack is too far from my broiler). Does anyone know what I can use to raise my steel plate? I was thinking about removing my oven racks, stacking three sets of fire bricks on the oven floor and then placing the plate on top of the stacks. (I worry about placing the bricks on top of the oven rack because the excess weight might break my rack.) Any other (better) ideas are welcome.
