Do you know what are pizza stones made of?

Tailored to retain heat, pizza stones help you whip up a perfectly crunchy and flaky crust without having to sacrifice the soft and biscuity interiors.

But which one is the best material?

Let’s examine deeper.

What are Pizza Stones Made Of?

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.

Pro Tip


Choose a pizza stone that meets your needs and that is multipurpose.

What Are Pizza Stones Made Of?

As with everything else, pizza stones are available in a wide array of shapes, structures, and sizes. Pizza stones are made from various materials like clay, granite, cast iron, cordierite, granite, marble, and more.

What are pizza stones made of?

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.

What are pizza stones made of? – Clay

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.

The result: 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 has durability issues as well. Cleaning these stones, however, is fairly simple.

Pros and Cons of Clay Pizza Stones

Pros

  • Excellent moisture-retaining properties.
  • Leaves you with crunchy and sog-free pizzas.
  • Available at an affordable price point.

Cons

  • May incur damages from the thermal shock.
  • Takes time to heat up

Ceramic Pizza Stones

Ceramic Pizza Pan

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

What are pizza stones made of? – Ceramic

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 their heat retention and conduction capabilities 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 the claystone, ceramic pizza stones take ages to pre-heat, and they 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.

Pros and Cons of Ceramic Pizza Stones

Pros

  • Cooks fast and evenly.
  • Available in a variety of styles and designs.
  • Easy to use and affordable.

Cons

  • Extremely high maintenance.
  • Not as durable.

A friend of mine used to install kitchen work surfaces but he was arrested for counter fitting.

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.

What are pizza stones made of? – Cast-iron

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.

To be classified as cast iron, a mainly iron alloy must have more than 2% carbon in the finished alloy. 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. All you need to do is 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!

Pros and Cons of Cast-Iron Pizza Stones

Pros

  • Extremely durable
  • Highest heat retention
  • Super easy to clean
  • Best cooking performance

Cons

  • Expensive
  • May rust over time

Cordierite Pizza Stones

What are Pizza Stones Made of

Are you wondering what are pizza stones made of? Known for their thermal shock resistance, cordierite stones can help you bake the crispiest pizzas.

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.

What are pizza stones made of? – Cordierite

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.

Pros and Cons of Cordierite Pizza Stones

Pros

  • Can withstand thermal shock and high heat
  • Efficiently retains heat.
  • Moisture retention capacity prevents sogginess in pizza crust.
  • Highly durable.

Cons

  • Can be slightly exhaustive to maintain.
  • Less resistant to temperature shock.
  • Not resistant to moisture, shouldn’t get wet.

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.

What are pizza stones made of? – Steel

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 that it will cook faster, regulate oven temperatures better, and be better when you use it for cold purposes.

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

Pros and Cons of Steel Pizza Stones

Pros

  • It heats up faster than a cordierite stone.
  • Very easy to clean
  • Efficiently retains heat.
  • Easy storage, you may leave it in the oven.
  • Highly durable.

Cons

  • Loses temperature quicker than a pizza stone.
  • It comes with a price tag


Granite Pizza Stones

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

What are pizza stones made of? – Granite

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

Available in a wide range of designs, they can also double up as a serving platter.

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

Pros and Cons of Granite Pizza Stones

Pros

  • Durable and easy to maintain
  • Absorbs and retains heat quite well
  • Can double up as a serving platter

Cons

  • Doesn’t retain moisture
  • Takes extremely long to heat up

Marble Pizza Stones

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

What are pizza stones made of? – Marble

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.

Pros and Cons of Marble Pizza Stones

Pros

  • Available in a wide range of designs
  • Moderately durable
  • Affordable

Cons

  • Takes a long time to heat up
  • Exhaustive maintenance

Unglazed Quarry Tiles

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

What are pizza stones made of? – Quarry Tiles

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; also, quarry tiles do not have a top glaze layer, unlike ceramic tile and porcelain.

The pizzas baked on these tiles are super crunchy, and they are ideal for making thin-crust pizzas. The downsides? Most of these titles aren’t very durable, and they 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.

Pros and Cons of Unglazed Quarry Tiles

Pros

  • Available in a wide range of designs
  • Moderately durable
  • Affordable

Cons

  • Takes a long time to heat up
  • Exhaustive maintenance


Here are Our Recommended Unglazed Quarry Tiles

What Is The Best Pizza Stone Material?

When it comes to the best pizza stone material, Steel is a clear winner. It heats up faster than any other material, it easy to clean, and requires less maintenance than any other material.  It sure will lose temperature quickly as well, but if you are doing one to two pizzas is perfect. 

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. 

Here is What the PROs at Homemade Pizza Pro Use and Recommend
