Wood-fired ovens, such as traditional pizza ovens, commonly use fire bricks in the inner construction around the oven chamber. Fire bricks are used in the cooking floor as well as the dome or roof of pizza ovens, and are able to withstand the thermal cycling (rapid heat up and cool down) that wood-fired ovens experience. Using fire bricks in wood-fired ovens makes the oven last a lot longer, and they can easily withstand the average 900 degrees Fahrenheit that these ovens reach.
