Top Reasons Why Pizza Stones Crack


When you throw a cold pizza stone into a hot oven, your stone experiences the dreaded "thermal shock," which basically means your stone can't handle large temperature changes. Since it's usually made of ceramic, that can cause a fracture in the stone. Sometimes it's evident immediately. Other times it lies dormant until your next baking session.


You should never wash your baking stone, because if the stone isn't allowed to dry appropriately before the next baking session, it can weaken the stone. Also, contrary to some old-wives' advice out there on the interwebs, never oil your baking stone. That's a one-way ticket to Cracksville.


Even if you've pre-heated your stone, you want to be careful about placing cool pizza dough onto it. And especially be cautious with placing frozen pizza dough on there. That'll rock your stone quicker than you can say "thermal shock.'


Even though with a name like "stone," you may expect your baking stone to be tough as nails, it's really much more fragile than you may think. Repeated handling of the stone can weaken its internal integrity over time. And, of course, the results don't show up until you're in the middle of baking that perfect pizza with company on the way. It's just how the world works, right?


Just like throwing a cold pizza stone into a hot oven can shock the senses out of it, pulling it out of a hot oven and setting it on the stove to cool can have a similar impact. It's just not ready for that kind of sudden temperature change.


This is a really unfortunate one, because the hotter you can get your oven, the quicker your pizzas will bake. And, you'll get that perfect crust. There's a reason wood fire ovens get up to 800 degrees! You need heat to turn out the perfect pizza! The bad news for your baking stone, though, is when you start to crank up the heat, you run the risk of shattering it into a few interestingly-shaped pieces.

Instead of being so negative, though, let me spell it out for you in positive terms how you should treat your pizza stone.

How To Prevent Your Pizza Stone From Cracking In The Future

  1. Keep your Pizza Stone in your oven all the time. If you like a pretty looking stone, cover with foil so drips from other things don't stain it.

  2. Always put a Pizza Stone into a cold oven and do a long pre-heat.

  3. Minimize handling. Moving in and out of the oven can cause cracking.

  4. Handle carefully. Any kind of drop will cause fractures.

  5. Avoid washing or oiling a Pizza Stone. The moisture can cause it to crack.

  6. Use only dough that is room temperature or warmer. (Some have even suggested warming it slightly on the stove top before placing it on the stone.)

  7. Wait until the Pizza Stone is completely cold before removing it from oven.

  8. Don't put frozen pizzas on your pizza stone. Ever.

  9. Use a folded towel and place on the counter before you take the stone out of the oven, so the counter won't send your stone into "thermal shock."

  10. Don't use high heat with it. (This one's kind of a bummer, since high heat makes unbelievable pizza pies!)

  11. If you leave your Pizza Stone in the oven, remove it for the self-cleaning cycle. With the drastic temperature changes, you're asking for trouble.

Are Pizza Stones Worth This Kind Of Kid-Glove Treatment?

If you've made pizzas on your baking stone, you'd probably answer with a hearty, "yes." You're a die-hard fan. Let's face it, pizza stones work pretty well. They have quite a bit more thermal mass than a baking sheet, so they store and distribute heat better than a flimsy metal pizza pan. (That "thermal mass" part is pretty important. That's where the magic happens.) The stone gets about as close to the the results of cooking a pizza in a brick oven as you can reasonably get, and usually gives you a decent looking crust and a nice tasting pie.

Make Even Bake Better Pizzas And Never Face A Fractured Stone Again

So, here's where the news goes from kind of bad to unbelievably good. Several years back, Modernist Cuisine published some findings from their research that if you wanted to make truly amazing New York Style pizza at home, you should skip the ever-present baking stone, and opt for baking your pizzas on a piece of steel. Steel has many times more thermal mass than a ceramic stone, which means it retains heat way better than a simple baking stone and does all the stuff that makes great pizza great. Plus, it's practically indestructible. I mean, you could probably crack it with some sort of anti-aircraft missile or a near-proximity nuclear detonation, but you shouldn't be cooking with that kind of stuff anyway.

Since we love making amazing pizzas, and we hate cracking pizza stones, we went looking for someone making a baking steel, and couldn't find anyone. So, we made it ourselves. Now, we're excited to help other pizza enthusiasts make the best pizzas of their lives at home with the Baking Steel. The Baking Steel is being snapped up all around the world by novices and pros alike, and the positive reviews for it have been truly overwhelming. You owe it to yourself to at least see what you may be missing by simply replacing that cracked pizza stone. We're pretty sure you'll never want to buy another stone again.
