Do you need fire bricks for a pizza oven?

Dry fitting the brick allows you to set up and take down the structure at your convenience. Materials required are approximately (depending on the size of the oven you build ) 100 to 250 clay bricks, 36” to 48” angle-iron, 2 pieces of 4’x4′ concrete board and approximately 20 to 25 8” concrete blocks.
