Emile Henry Pizza Stones: What They Are and How to Use Them in Your Refrigerator

Emile Henry makes ceramic pizza stones that work differently than traditional clay

Emile Henry is a French cookware manufacturer known for high-fired ceramic bakeware, including pizza stones. Their stones are made from a proprietary ceramic blend fired at very high temperatures, which makes them denser and more durable than standard terracotta or low-fire clay. This density means they heat more evenly, retain heat longer, and are less likely to crack from thermal shock — the sudden temperature change that happens when you move a cold stone into a hot oven.

The brand's pizza stones come in several sizes and shapes, from round to rectangular, and they're designed to work in home ovens, not just commercial ones. Because they're ceramic rather than porous clay, they behave differently during storage and cleaning, which matters if you're keeping one in or near your refrigerator between uses.

Key Takeaways

• Emile Henry stones are made from dense, high-fired ceramic that resists cracking and heats more evenly than standard clay pizza stones.
• These stones should not be stored in a refrigerator or freezer because rapid temperature changes can cause the ceramic to crack, even though the material is more durable than clay.
• After use, let an Emile Henry stone cool completely at room temperature before washing or storing it, which typically takes one to two hours.
• The ceramic surface can be wiped clean with a damp cloth or scrubbed gently; avoid soaking or putting it in a dishwasher.

Why temperature swings matter for Emile Henry stones

Even though Emile Henry ceramic is tougher than standard pizza stone clay, it still expands and contracts with temperature. When you pull a hot stone from a 500-degree oven and expose it to cold air — or worse, cold water — the outer surface cools faster than the interior. This uneven cooling creates stress in the material, and over time or with a sudden shock, that stress can cause hairline cracks or a full break.

Storing a stone in a refrigerator or freezer accelerates this problem. The cold environment means the stone stays cold, and when you move it to a hot oven, the temperature difference is extreme. Even one cycle of cold storage followed by high-heat cooking can damage the stone, so the safest approach is to keep it at room temperature between uses.

Proper storage location for your Emile Henry stone

Store your Emile Henry pizza stone in a cool, dry place at room temperature — a kitchen cabinet, pantry shelf, or countertop works well. The stone should be flat and supported so it doesn't rest on an edge or corner, which concentrates weight and increases the risk of chipping. If you stack other items on top of it, use a thin cloth or paper towel as a buffer to prevent scratching.

Avoid storing the stone in damp areas like under a sink or in a basement with high humidity. While the ceramic itself won't absorb water the way porous clay does, moisture can collect on the surface and promote mold growth if the stone sits unused for weeks. A dry kitchen shelf is ideal.

Cooling and cleaning after each use

After you finish cooking, turn off the oven and leave the stone inside to cool. Do not remove it while it's hot. Let it sit in the cooling oven for at least one to two hours until it reaches room temperature — you should be able to touch it comfortably with your bare hand. This slow, gradual cooling prevents the thermal shock that causes cracks.

Once the stone is cool, wipe the surface with a damp cloth to remove flour, cornmeal, or food residue. For stubborn spots, use a soft brush or non-abrasive scrubber. Do not soak the stone in water, and do not put it in a dishwasher. If you need to remove baked-on food, let the stone sit at room temperature for a few hours, then scrub gently with a damp cloth and a little baking soda. Dry it completely with a towel before storing.

Differences between Emile Henry and standard clay stones

Standard terracotta or low-fire clay pizza stones are porous, which means they absorb water and oils from food. Over time, this absorption can cause discoloration and odors. Emile Henry's high-fired ceramic is much less porous, so it resists staining and doesn't retain food smells as easily. This also means you don't need to season an Emile Henry stone the way you might a clay one.

The trade-off is that Emile Henry stones cost more than basic clay alternatives. However, they last longer, perform more consistently, and require less maintenance. If you use your pizza stone regularly, the durability and even heat distribution often justify the higher price.

What to avoid with your Emile Henry stone

Never use your Emile Henry stone on a stovetop, under a broiler, or directly over a flame. The stone is designed for oven use only, where heat surrounds it evenly. Direct, intense heat from below can cause cracking or warping.

Do not use oil, butter, or cooking spray on the stone surface. These can smoke at high temperatures and leave a sticky residue that's hard to clean. If you want to prevent sticking, dust the stone lightly with cornmeal or flour before placing dough on it. Do not use metal utensils or sharp tools to scrape the surface, as these can chip the ceramic. A wooden or silicone pizza peel is the best tool for moving pizzas on and off the stone.

Preheating and cooking with Emile Henry stones

Place your Emile Henry stone on the middle or lower rack of your oven and preheat it for at least 30 to 45 minutes before cooking. The dense ceramic takes longer to heat through than thin clay, so don't rush this step. Once the oven reaches your target temperature, the stone will be ready to use.

You can cook multiple pizzas on the same stone without removing it from the oven, as long as you allow a few minutes between pizzas for the stone to recover its heat. The ceramic's heat retention means it bounces back quickly, so you won't see a big temperature drop between batches.

Frequently Asked Questions

Can I put my Emile Henry stone in the refrigerator to speed up cooling?

No. Putting a hot or warm stone in a refrigerator causes rapid temperature change that can crack the ceramic, even though Emile Henry material is more durable than standard clay. Always let the stone cool at room temperature for one to two hours after cooking.

Will my Emile Henry stone crack if I use it in a very hot oven?

Emile Henry stones are designed for home ovens up to around 500 degrees Fahrenheit and can handle that temperature safely. Cracks usually result from thermal shock — sudden temperature changes — not from steady high heat. As long as you preheat the stone and let it cool slowly, it should remain intact.

Do I need to season an Emile Henry pizza stone?

No. Unlike porous clay stones, Emile Henry's high-fired ceramic doesn't require seasoning. Simply wipe it clean after each use and store it dry. Over time, the surface may develop a patina from cooking, but this is normal and doesn't affect performance.

What should I do if my Emile Henry stone develops a crack?

A small hairline crack won't affect cooking much, but the stone may eventually break further. If the crack is large or the stone is broken into pieces, it's no longer safe to use. Emile Henry offers replacement stones, and you can contact the manufacturer for warranty information if the stone failed prematurely.

Can I use my Emile Henry stone for baking bread or other foods besides pizza?

Yes. Emile Henry pizza stones work well for bread, biscuits, cookies, and other baked goods. The same cooling and storage rules apply — let it cool at room temperature and store it in a dry place away from temperature extremes.
