A baking stone is a portable cooking surface used in
baking
Baking is a method of preparing food that uses dry heat, typically in an oven, but can also be done in hot ashes, or on hot stones. The most common baked item is bread but many other types of foods can be baked. Heat is gradually transferred " ...
. It may be made of
ceramic,
stone or, more recently,
salt.
Food is put on the stone, which is then placed in an oven, though sometimes the stone is heated first.
Baking stones are used much like
cookie sheets, but may absorb additional moisture for crispier food.
A pizza stone is a baking stone designed for cooking pizza.

Due to the
thermal mass of baking stones and the material's property as a poor heat conductor,

bakeware. Baking stones are a variation on hot stone cooking, which is one of the oldest cooking techniques known. Some cooks recommend sprinkling
corn meal or flour on the baking stone to prevent the crust from sticking or using
parchment paper atop the stone.
Baking "stones" may be purchased as unglazed
ceramic tiles
Tiles are usually thin, square or rectangular coverings manufactured from hard-wearing material such as ceramic, stone, metal, baked clay, or even glass. They are generally fixed in place in an array to cover roofs, floors, walls, edges, or o ...

hardware stores.
To prevent
fracturing of the stone by
thermal shock
Thermal shock is a type of rapidly transient mechanical load.
By definition, it is a mechanical load caused by a rapid change of temperature of a certain point.
It can be also extended to the case of a thermal gradient, which makes different pa ...
, some bakers place the baking stone in a cold oven and heat it over at least 45 minutes,
then allow it to cool slowly inside the oven after switching it off. Because of the possibility of rapid temperature change, baking stones should not be left in an oven while it is in
self cleaning mode.
Baking stones can be cleaned with a dry
brush or
scouring pad followed by plain
hot water
Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated t ...

Pizza stone
When designed for cooking
pizzas, a baking stone is often referred to as a pizza stone. Using a pizza stone more or less mimics the effects of cooking a pizza in a
masonry oven. The
porous nature of the stone absorbs
moisture
Moisture is the presence of a liquid, especially water, often in trace amounts. Small amounts of water may be found, for example, in the air (humidity), in foods, and in some commercial products. Moisture also refers to the amount of water vapo ...
, resulting in a crispier crust. Small pizza stones can be purchased to fit any conventional cooking
oven or an enclosed
barbecue-style grill. High-end ovens sometimes offer optional pizza stones that are specifically designed for each oven model and may include a specialized
heating element
A heating element converts electrical energy into heat through the process of Joule heating. Electric current through the element encounters resistance, resulting in heating of the element. Unlike the Peltier effect, this process is independe ...

Pizza / baking steel
A36 steel plate usually long x wide x thick, It conducts heat better than stone, is safe to use under any broiler and on the grill, but gives off too much heat for bread, cookies, and croissants. It is carbon steel, so also heavier, needs to be pre-seasoned before use.
