Continue reading to uncover the secret ingredients behind the magic of pizza stones and how they contribute to transforming your homemade pizzas into pizzeria-style masterpieces.

Let’s examine it deeper.

You can slow cook, broil, bake, grill, and roast practically anything in your home oven.

But when it comes to making a pizza, home ovens do not make the cut.

Without the right baking surface that will be perfectly hot for your pizza, you can never develop the treat’s right consistency.

And this is where a pizza stone can be of help.

Pizza stones are typically made of ceramic, cordierite, or clay. These materials have unique characteristics that make them suitable for baking pizzas.

Ceramic

This is the most common material used for pizza stones. Ceramic has excellent heat retention properties, allowing for even cooking. It also absorbs moisture from the pizza dough, producing a crispier crust.

Cordierite

This material is more durable and resistant to thermal shock than ceramic, meaning it’s less likely to crack from rapid changes in temperature. Cordierite stones are often a bit more expensive than their ceramic counterparts, but their durability makes them popular.

Clay

Some pizza stones are made from clay, particularly fireclay, which can withstand very high temperatures. Clay stones tend to heat slowly but retain and distribute heat exceptionally well.

Regardless of the material, pizza stones mimic the conditions of a brick oven, making them an excellent tool for baking pizzas with a well-browned, crispy crust. It’s important to note that pizza stones require careful handling and specific cleaning methods to keep them in good condition.

Are you wondering what are pizza stones made of? But which among these options is the best pizza stone material? And which one should you invest in?

Read on to find out more about each material with a detailed analysis of its pros and cons.

Clay Pizza Stones

If you’re a home baker who’s looking to whip up some delicious pizzas, a clay pizza stone might be your best option.

Clay minerals are primarily made up of silica, alumina or magnesia (or both), and water, while iron substitutes for aluminum and magnesium to variable degrees, and potassium, sodium, and calcium are commonly present.

With excellent moisture-retaining properties, clay pizza stones specifically ensure that your pizzas are crunchy through and through.

You are left with a deliciously crunchy exterior paired with a soft crust.

The downsides?

It takes a little too much time for pre-heating, and in some instances, it also has durability issues. Cleaning these stones, however, is fairly simple.

Ceramic Pizza Stones

Ceramic pizza trays are created through a rigorous clay baking session. Once baked, the clay is then hardened to render a structure.

Ceramics are often manufactured by molding clay, earthy materials, powders, and water mixes into desired shapes. After the ceramic has been molded, it is burnt in a kiln, which is a high-temperature oven.

Glazes are ornamental, waterproof, paint-like substances that are applied to ceramics.

Most ceramic stones are widely used for heat retention and conduction at high temperatures. Thanks to these stones, heat is evenly radiated, leaving you with a perfectly cooked pizza.

While ceramic stones are not known to be traditionally durable, they will last a while when you properly care for them.

They may be subjected to thermal shock, and you will require extra care while cleaning and maintaining them.

As with claystone, ceramic pizza stones take ages to pre-heat and aren’t as potent to handle massive temperature changes.

But then again, these stones are cheap, and if it’s a basic stone that you require, they will turn out as just the right option.

Cast-Iron Pizza Stones

If crispy and crunchy crusts are what you look forward to, a cast iron pizza stone might be a truly valuable addition. Thanks to nifty little tools, baking a restaurant-style pizza is now a breeze!

The best part: you can also double up your cast iron pan like a pizza stone.

Cast iron is a word that refers to a group of metal alloys that include iron as their major alloying ingredient. Some people mistakenly believe that cast iron is made entirely of iron because of its name. This simply isn’t the case. Carbon steels, in fact, have a larger percentage of iron than cast iron.

A mainly iron alloy must have more than 2% carbon in the finished alloy to be classified as cast iron. Other alloys, such as manganese and silicon, are also present in lower proportions in cast irons.

The most defining point of cat iron stones is that they heat up really well, leaving you with a crunchy exterior. They also feature handles, further making way for ease of use and convenience.

Again, cast iron is practically impossible to tamper with. Unlike your clay or ceramic pizza stones, these devices won’t ever crack, no matter how hot your oven is.

Finally, the biggest takeaway of steel pizza stones is that they are super simple to clean. You must wipe them off with a clean towel after seasoning them with a dash of oil and salt.

With these stones in place, you can bid farewell to scrub forever!

The only minor issue with these stones is that they can be heavy.

Other than this, they are outstanding to go!

Cordierite Pizza Stones

Are you wondering what are pizza stones made of? Cordierite stones can help you bake the crispiest pizzas because they are known for their thermal shock resistance.

They can handle extreme temperatures, and unlike ceramic stones, they won’t break down during temperature transitions.

The stone, however, requires some degree of maintenance and proper cleaning for maximized durability.

Cordierite is a naturally occurring mineral compound containing magnesium, iron, aluminum, and silicon.

In addition to absorbing heat, cordierite stones also efficiently retain moisture, preventing sogginess in the curst. The downsides?

The maintenance options, that’s it. These stones heat up really well, and thanks to their even radiation, you’re left with some of the most delicious pizzas.

Steel Pizza Stones

Steel conducts heat evenly and quickly, making it excellent when it comes to baking pizza. It is also almost indestructible, making it an excellent investment for a piece of kitchen equipment.

Steel is an alloy made up of iron with typically a few tenths of a percent of carbon to improve its strength and fracture resistance compared to other forms of iron.

The steel heats very efficiently. The heat from the steel will move quickly to the pizza crust that is resting on its surface.

This heating method will shorten your cook time versus using a baking stone. You can also use the steel as a griddle on your stovetop or even try freezing it to try new cooking techniques.

Baking steels come in a few different thicknesses.

Thicker steel will hold more energy, meaning it will cook faster, regulate oven temperatures better, and be better when used for cold purposes.

Just like stone, thicker steel will typically be more expensive.

Granite Pizza Stones

Granite stones are known for their heat retention and heat absorption properties.

Granite is a coarse-grained intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high silica and alkali metal oxide content that slowly cools and solidifies underground. 

Available in various designs, they can also double up as a serving platter.

These stones are also scratch-resistant, durable, and super easy to clean. The downside? They do not absorb moisture, so you might not get the crunchiest crusts.

Marble Pizza Stones

Marble pizza stones are incredibly delicate and can take ages to clean. However, this might be a good option if you are looking for a cheap stone for occasionally baking pizzas.

Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite.

Marble stones take ages to heat up, and although they are somewhat durable, you wouldn’t want to count on them. Cleaning them is equally exhaustive.

Unglazed Quarry Tiles

Unglazed quarry tiles might be your best option if you are looking for a cheap, DIY option for baking pizzas. Ideally, you will need four eight-inch tiles to make a large pizza tray.

Quarry tile is a tough, impermeable pavement tile created from pulverized minerals that are molded and burned in the same manner as bricks are.

Because of the minerals utilized and the high firing temperatures, they are often tougher than conventional clay bricks.

Quarry tiles, unlike clay terracotta, are not porous and will not absorb water; quarry tiles do not have a top glaze layer, unlike ceramic tile and porcelain.

The pizzas baked on these tiles are super crunchy and ideal for making thin-crust pizzas. The downsides? Most of these titles aren’t very durable and take ages to heat up.

While the regular cracks on the tiles may render an authentic taste to your pizzas, cleaning them is nothing short of a nightmare.

Additional pizza may require additional baking time. However, a minute or two will do, which we don’t think makes much of a difference in the scheme of things.

This durable metal stone will ensure even heating, leaving you with the tastiest pizzas.

Cordierite is a close second with its substantial heat retention capability. Although they are slightly cumbersome to maintain, they continue to stand out with their excellent thermal shock absorption properties and high durability.

Are you having a pizza party?

If you need to make a substantial amount of pizzas, then Cordiarite is the way to go.  This stone will not lose much efficiency when you keep opening and closing the oven.
