How Your Pizza Oven Baking Tiles Work

Firebricks are made by compressing refractory clays in a form, and firing it in a kiln. At high pressure and high temperature, the basic chemistry of the clay is transformed (it’s call Sintering) into a new material that is both durable and efficient at storing heat and transferring to food, including pizza and bread dough. A firebrick is very durable and resistant to high temperatures, fire and coals. Firebrick baking tiles are different from industrial firebricks, because they are designed to operate in the moderate temperature ranges you see in a pizza oven and to work will in the day-to-day operation of a residential pizza oven.

For example, a residential pizza oven is fired from scratch every time it is used, so a pizza oven baking tile is designed to be resilient to thermal cycling (from zero to 700F, and back to zero), where an industrial firebrick is often installed in a furnace that is held at high temperature its entire life. Equally, a pizza oven baking tile is designed to be resilient to thermal shock — putting cold, wet pizza and bread dough on a hot baking tile cooking floor. Thermal shock can lead to an industrial firebrick breaking its ceramic bonds, which leads to spalling, or flaking over time. Of course this is fine for a firebrick designed for a furnace (where pizzas will not be constantly put on the furnace wall!), but not for a pizza oven cooking floor. And finally, a firebrick baking tile must be resistant to physical abrasion — cleaning your cooking floor with a brush.

Your Bella pizza oven has a great firebrick baking tile cooking floor, that will make great pizza and crusty bread and will last the lifetime of your oven.
