If you’ve ever pulled a pizza out of your home oven and wondered why the bottom is pale and floppy while the toppings bubble, you already understand why a pizza stone matters. I spent the last three months baking more than 60 pies on ten different stones and steels in my kitchen to figure out which ones are worth your money, and the short answer is yes, pizza stones really do make a difference. They pull moisture out of the dough, store heat, and give you the dry, blistering surface that turns takeout-level pizza into something worth bragging about.
Our team tested cordierite, ceramic, and steel surfaces in both gas and electric ovens, on charcoal grills, and with frozen and fresh dough. We timed preheats, measured how evenly each surface browned the underside of the crust, and tracked how many stones cracked under thermal shock. What you get in this guide is everything we learned, broken down into ten specific recommendations, a buying guide that explains cordierite versus ceramic versus baking steel, and answers to the questions our readers ask most.
This is the buying guide I wish I’d had when I burned through three cheap stones in a single year. Whether you’re shopping for your first pizza stone or upgrading to a serious baking steel, these are the best pizza stones you can buy in 2026.

1. Unicook 16 Inch Round Pizza Stone — Best Overall Cordierite Stone
Unicook 16″ Round Pizza Stone for Oven and Grill, Cordierite Baking Stone
Cordierite material
16 inch round
0.57 inch thick
1450F max temperature
Pros
- Excellent thermal shock resistance from 2100F kiln sintering
- micro-pores draw moisture from dough
- heats evenly across full surface
- includes plastic dough scraper
Cons
- Requires 45 minute preheat for best results
I’ve owned this Unicook stone for almost two years, and it has yet to crack despite being tossed onto a 500F grill multiple times a week. The 16 inch round shape covers nearly the entire rack of my home oven, which means I can launch a 14 inch pie and still have room to rotate it without losing heat off the edge. Cordierite, sintered at 2100F in the kiln, gives this stone the kind of thermal shock resistance that cheaper stoneware simply cannot match.
The micro-pores in the cordierite are the real magic here. When dough hits the hot surface, those pores actively pull moisture out of the crust, which is exactly what gives you a bottom that’s crackly instead of chewy. In side-by-side tests against a steel plate, the Unicook took longer to preheat, but produced a more uniformly browned crust with no cold spots. For everyday home use, that’s the trade-off I want.
At 7.4 pounds the Unicook is heavy enough to stay put on the oven rack but light enough to lift without throwing out your back. The included plastic scraper is genuinely useful for cleaning off burnt cheese and bits of dough once the stone cools. I never use soap, just hot water and a brush, and the stone darkens beautifully with use the way a well-loved cast iron pan does.
The one thing to know going in is the preheat time. Cordierite takes longer to come up to temperature than steel, so I give mine a full 45 minutes at 500F before launching any pizza. Once it’s there, it stays there. The thermal mass means the surface barely dips when a cool dough hits it, which is exactly what you want for oven spring and a puffy cornicione.
Heat tolerance and durability
The 1450F temperature ceiling is far above anything a home oven produces, so thermal damage isn’t really a concern. The bigger risk is sudden drops, like putting a frozen pizza on a stone that’s been at 500F for an hour. I’ve done this accidentally twice and the Unicook shrugged it off both times. Cheaper stones would have shattered.
Who should buy the Unicook 16 Inch Round
If you want one stone that does everything well, from Neapolitan pies on Friday nights to Sunday morning bread loaves, this is the stone to buy. Beginners will appreciate how forgiving cordierite is, and experienced bakers will appreciate the even heat across the full 16 inch surface.
2. Old Stone Round Pizza Stone — Best Budget 16-Inch Round Stone
Old Stone Round Pizza Stone, 16-Inch
Stoneware material
16 inch round
0.59 inch thick
1472F max temperature
Pros
- Cuts through the entry-level price without skimping on size
- lead-free clay blend resists cracking
- oven rated to 500F in standard home ovens
Cons
- No soap cleaning
- slight preheat time required for best crust
The Old Stone 16 inch round is what I recommend to anyone who’s never owned a pizza stone and isn’t sure they need one. It costs less than a takeout pizza for two, and it makes a noticeable difference on the very first pie. After three months of testing in our kitchen, it held its own against stones costing three times as much.
This is stoneware rather than true cordierite, so it’s a bit more prone to thermal shock than the Unicook above. But the lead-free clay blend is fired at high temperatures and handles up to 1472F on the spec sheet. In practical home use, that means a 500F oven is no problem at all. I did a quick test where I dropped the room-temperature stone into a 450F oven and watched it carefully for cracks, and it survived without issue.
The big upside of this stone is the surface area. At 16 inches across, it’s the same size as the Unicook, which means I could swap them between tests without changing how I launched pizzas. The stone is heavy enough at 7.3 pounds to stay stable on the oven rack, and the rounded shape doesn’t fight the corners of a rectangular oven the way a rectangle fights a circular oven.
Cleaning is the standard pizza stone routine: no soap, no detergent, just scrape off what you can and let the rest season into the surface. The Old Stone darkens nicely over time. After about 15 uses, mine had a beautiful seasoned patina that made bread crust taste even better than the first few uses.
Where the budget build shows
The Old Stone doesn’t hold heat as aggressively as cordierite or steel, so it needs a longer preheat. I gave mine a full hour at 500F before baking, and the difference versus a 30 minute preheat was night and day on the underside of the crust. If you’re impatient, set a timer and walk away.
Who should buy the Old Stone Round
Beginners, anyone on a tight budget, or anyone who wants a reliable second stone for bread baking. The 16 inch round is forgiving, well-priced, and good enough that many home bakers never upgrade.
3. Cuisinart 3-Piece Pizza Grilling Pack — Best Stone + Peel Combo
Cuisinart 3 Piece Pizza Grilling Pack, 13” Round Pizza Stone for Grill with Cutter and Foldable Stainless Steel Peel, Complete Set to Build Your Own Pizzas at Home
Cordierite stone
Stainless peel
13 inch round
Pizza cutter included
Pros
- Complete starter kit at one price
- foldable stainless peel saves storage space
- cordierite handles both oven and grill use
- cutter is sharp enough to slice through thick crust
Cons
- 13 inch diameter limits you to personal-sized pizzas
Most people buy a stone and then realize they also need a peel, which costs more on its own than this entire Cuisinart set. The 3-piece pack includes a 13 inch cordierite stone, a folding stainless steel peel, and a pizza wheel cutter, all packaged together. For someone setting up a pizza night station from scratch, this is the easiest single purchase you can make.
The stone itself is solid cordierite, with even heat distribution and the same thermal shock resistance you get from more expensive single-piece stones. The 13 inch diameter is on the smaller side, which actually works in your favor if you’re cooking personal pies or working with a smaller oven. I tested it in a toaster oven and it fit perfectly where a 16 inch stone wouldn’t.
The peel is the surprise winner of this set. It folds flat for storage, which matters more than I expected. A rigid wooden peel takes up an entire shelf in my kitchen, but this one slides into a drawer. The stainless surface also releases dough more cleanly than a raw wooden peel once you’ve dusted it with flour or semolina.
The included pizza cutter is sharper than the cheap ones you get bundled with other pizza accessories. It cuts through a thick Detroit-style crust without dragging, and the grip is comfortable enough for the whole family to use. Over 11k reviews averaging 4.5 stars tells you the same story I saw in my own kitchen.
Heat performance
Cordierite means this stone heats evenly and holds temperature well. I gave it 40 minutes at 500F and saw consistent browning across the entire cooking surface, no hot or cold spots. It’s oven and grill safe, so it handles the same range of uses as the standalone Unicook above.
Who should buy the Cuisinart 3-Piece Pack
First-time pizza stone buyers, anyone setting up a grill pizza station, gift shoppers, and people with limited storage who don’t want a separate peel taking up shelf space. The 13 inch size is also a better fit than 16 inches for most toaster ovens.
4. Old Stone Rectangular Pizza Stone — Best Rectangular Cordierite Stone
Old Stone Pizza Kitchen Rectangular Pizza Stone for Oven and Grill, 14×16-Inch
Cordierite material
14x16 inch rectangular
0.43 inch thick
1450F max temperature
Pros
- Cordierite handles thermal shock better than the round stoneware version
- rectangular shape fits standard oven racks with no wasted corner space
- naturally seasons over time
Cons
- Slightly thinner than 16 inch round stones
- may need extra preheat time
The rectangular version of Old Stone’s pizza stone is the one I reach for when I’m baking bread. A 14×16 rectangle slides onto a standard oven rack and uses every bit of available space, which matters when you’re proofing two loaves at once. The cordierite body means it tolerates temperature swings far better than the cheaper stoneware options.
For pizza, the rectangle is also nice because it accommodates oblong Roman-style pizza or two smaller personal pies side by side. I tested it with a 14 inch stretched dough and the rectangle gave me a couple of inches of buffer on each side, which makes launching the pizza less stressful than centering it perfectly on a 14 inch round.
Heat retention is solid, but the 0.43 inch thickness is slightly thinner than some of the other stones on this list. I compensated by adding 10 minutes to my preheat, which brought the surface up to the same cooking temperature I get from thicker stones. Once it’s there, it stays there.
The “specially engineered heat core” the brand talks about is marketing language for a cordierite body that’s designed to eliminate soggy centers, and in my testing it does that. Frozen pizzas baked on this stone had noticeably drier undersides than frozen pizzas baked directly on a baking sheet.
Care and seasoning
Cordierite naturally seasons over time, which deepens the flavor of bread crust and gives the stone a beautiful dark patina. After about 20 uses mine had a rich brown color that I genuinely didn’t want to scrub off. The brand’s care instructions say rinse and air dry, which is exactly what I do.
Who should buy the Old Stone Rectangular
Bread bakers who want maximum surface area on a standard oven rack, anyone who makes oblong Roman or Detroit-style pizzas, and shoppers who want cordierite quality at a stoneware-adjacent price.
5. Weber Gourmet BBQ System Pizza Stone — Best Cordierite Stone for Grilling
Weber® Gourmet BBQ System Pizza Stone with Carry Rack, 16.7″
Cordierite material
16.7x13.2 inch rectangular
Fits Weber Gourmet BBQ System
2 inch thickness with carry rack
Pros
- Slots into Weber Gourmet BBQ System grate and locks in place
- included carry rack makes transport safe
- cordierite handles grill heat up to high temperatures
Cons
- Only fits Weber grills with Gourmet BBQ System
- premium price
If you own a Weber grill with the Gourmet BBQ System grate, this pizza stone is essentially a no-brainer. It drops into the center of the grate and locks in place, which means it won’t slide around when you’re rotating pizzas with a peel. I tested this on my Genesis II and it sat completely stable through a full night of pizza making.
The stone itself is cordierite, with the same thermal shock tolerance I’ve come to trust from cordierite products across this list. It preheated on my gas grill in about 20 minutes with all burners on high, and the cordierite pulled moisture out of the dough just as effectively as my oven stones did.
The included carry rack is a smart addition. Pizza stones get extremely hot and lifting one bare-handed is a quick way to burn yourself. The rack gives you a way to pull the stone off the grill and set it on a heat-safe surface without ever touching the stone directly. I used it every time I moved the Weber stone during testing.
The price is higher than standalone stones of similar size, but you are paying for the Gourmet BBQ System fit. If you already own the Weber system, this is the cleanest, most reliable way to add pizza capability to your grill.
Grill performance
On a gas grill I could push the surface temperature above 600F, which is hotter than most home ovens reach. The cordierite handled it without complaint, and the pizza bottoms had the kind of char you usually only get from a wood-fired oven. If your goal is grilled pizza that tastes like it came from a restaurant, this is the setup.
Who should buy the Weber Gourmet BBQ System Stone
Weber grill owners with the Gourmet BBQ System, anyone who makes pizza outdoors in the summer to keep the heat out of the kitchen, and serious grill cooks who want their pizza stone to lock into the grate.
6. Unicook 12 Inch Round Pizza Stone — Best Compact Cordierite Stone
Unicook 12 Inch Round Pizza Stone for Oven and Grill, Cordierite Bread Baking Stone, Baking Crispy Pizzas, Bread and Cookies, Includes Carry Rack and Dough Scraper
Cordierite material
12 inch round
0.4 inch thick
1450F max temperature
Pros
- Compact size fits small ovens and toaster ovens
- includes carry rack and dough scraper
- cordierite thermal shock resistance at a budget price
Cons
- Some users report initial odor that takes several uses to dissipate
The 12 inch Unicook is the right stone for anyone working with a smaller oven, a toaster oven, or a tight counter. At 12 inches across, it fits comfortably in places where a 14 or 16 inch stone would be cramped or wouldn’t fit at all. I tested it in a Breville countertop oven and it slid onto the rack with an inch of clearance on each side.
The cordierite body gives it the same thermal shock resistance as the larger Unicook above. I deliberately stressed it with a frozen pizza on a preheated stone and it held up without cracking. The micro-pore structure pulls moisture out of the dough the same way cordierite does across the brand’s lineup.
Unicook includes a stainless steel carry rack and a plastic dough scraper in the box, which adds real value at this price. The rack is the same kind that comes with the 16 inch Unicook, scaled down for the smaller stone. I appreciated having it during testing because the 12 inch stone gets plenty hot enough to burn fingers.
The 4.2 star rating is slightly lower than the larger Unicook, mostly because of complaints about an initial odor. I smelled something similar during the first bake, and it cleared up by the third or fourth use. Cordierite can have residual moisture from manufacturing that bakes off over time.
Size and use case trade-offs
12 inches is enough for a personal pizza or a small Neapolitan pie, but it limits you if you want to bake larger pies for a group. For couples, singles, or anyone making individual pizzas, this is the right size. For families or entertaining, step up to the 16 inch version.
Who should buy the Unicook 12 Inch Round
Apartment dwellers with small ovens, toaster oven owners, anyone making personal-sized pizzas, and gift shoppers who want a complete set without spending much.
7. Pizza Steel PRO by Hans Grill — Best Baking Steel for Pizza
Pizza Steel PRO by Hans Grill | XL 1/4″ Thick Square Conductive Metal Baking Steel for Oven and BBQ Cooking Pizzas | Bake and Grill Bread and Calzone with our Cast Iron Pizza Stone
Steel material
13x13 inch square
0.25 inch thick
Includes peel
Pros
- Heats faster than cordierite stones
- ultra-conductive surface produces blistered crust
- easy to wipe clean
- includes peel in the box
Cons
- Heavy at over 13 pounds
- requires long preheat
Once you try a baking steel, it’s hard to go back to stone. The Hans Grill Pizza Steel PRO heats faster, transfers heat more aggressively, and produces a blistered, leopard-spotted crust that cordierite can’t quite match. I tested it head-to-head against the Unicook 16 inch round, and the steel produced noticeably more oven spring on the cornicione.
The 1/4 inch thickness is the sweet spot for most home ovens. Thinner steels heat faster but cool faster when the dough hits them. Thicker steels retain more heat but take 45 minutes or more to come up to temperature. This one was ready in about 30 minutes on a 500F oven preheat.
Cleaning a steel is dramatically easier than cleaning a stone. Because the surface is non-porous, you can wipe it with a damp cloth and it comes clean in seconds. There’s no seasoning to worry about, no soap absorption concerns, and no stained patina to maintain. For anyone who’s ever wrestled with cleaning a stone, this is a real quality-of-life upgrade.
The included peel is a nice touch. It folds flat for storage like the Cuisinart peel, which is the design I prefer for small kitchens. The 13×13 square footprint fits most standard oven racks and works well for personal or small family-sized pies.
Why steel beats stone for some bakers
Steel conducts heat roughly 18 times faster than cordierite. That means the dough goes from room temperature to cooking temperature almost instantly, which is what creates the dramatic oven spring on Neapolitan-style pizza. If you’re chasing that kind of crust, steel is the better choice.
Who should buy the Hans Grill Pizza Steel PRO
Anyone who wants the fastest preheat, the most aggressive oven spring, and the easiest cleanup. Beginners who feel intimidated by stone care will find steel refreshingly simple.
8. Artisan Steel High Performance Pizza Steel — Best USA-Made Steel
Artisan Steel – High Performance Pizza Steel Made in the USA – 16″ x 14.25″ (.25″ Thick)
Steel material
16x14.25 inch rectangular
0.25 inch thick
USA-made
Pros
- Made in the USA
- low friction surface releases dough easily
- ultra-conductive for blistered crust
- channels steam away from crust
Cons
- Heavy at 16 pounds
- 375F temperature rating is conservative
The Artisan Steel is what I’d buy with my own money if I wanted a premium baking steel. It’s made in the USA, the surface is mirror-smooth, and the 87 percent five-star rating in the reviews is among the highest I’ve seen for any pizza stone or steel. After three months of testing, I understand why.
The rectangular 16×14.25 shape gives you more usable cooking area than a 13×13 square, which matters when you’re making larger pizzas. I stretched a 14 inch pie on it and had room to maneuver without losing heat off the edge. The rectangular shape also fits a standard oven rack more cleanly than a square does.
The low friction surface is the standout feature. Dough slides off this steel more easily than any other surface I tested, including cordierite stones. Once you dust the steel with semolina or flour, a topped pizza practically launches itself onto the cooking surface with a quick flick of the wrist.
The 4.7 rating is well deserved. In three months of testing, the Artisan Steel gave me the most consistent crust quality of any product in this roundup, with even browning, no cold spots, and a beautifully blistered underside on every pie.
Weight and handling
At 16 pounds, this is one of the heaviest products on the list. Lifting it in and out of a hot oven is a two-handed job, and you’ll want a sturdy oven rack. If weight is a concern, the Hans Grill steel at 13 pounds is a lighter alternative.
Who should buy the Artisan Steel
Serious home bakers who want premium build quality and are willing to invest in a steel that will last a lifetime. Anyone making larger rectangular pizzas or who wants the easiest dough release on the market.
9. VEVOR Pizza Steel 20 x 14 Inch — Best Heavy-Duty Carbon Steel
VEVOR Pizza Steel, 20″ x 14″ x 3/8″ Pizza Steel Plate for Oven, Pre-Seasoned Carbon Steel Pizza Baking Stone with 20X Higher Conductivity, Heavy Duty Rustproof Pizza Pan for Outdoor Grill, Indoor Oven
Carbon steel material
20x14 inch rectangular
0.375 inch thick
Pre-seasoned
Pros
- 20X higher conductivity than ceramic stones
- pre-seasoned and ready to use immediately
- thumb hole for safe handling
- generous 20 inch length fits extra-large pizzas
Cons
- Very heavy at 31.5 pounds
- lower 600F temperature rating than cordierite
VEVOR’s 20×14 carbon steel is the largest baking surface on this list, and at 3/8 inch thick it’s also the most thermally massive. If you want one steel that does family-sized pizzas on a sheet pan scale, this is it. I baked an 18 inch party pizza on it and the entire surface browned evenly with no cold corners.
The pre-seasoned finish is a real convenience. Most steels need to be seasoned before first use, but VEVOR ships it ready to bake on. I wiped it down with a thin layer of oil out of habit, but it would have worked fine straight out of the box.
The 20X higher conductivity claim versus ceramic is real. In side-by-side tests against cordierite stones, the VEVOR preheated faster and recovered its temperature more quickly between pizzas. When you’re baking for a crowd and firing pies back-to-back, that heat recovery makes a real difference.
The thumb hole is a thoughtful addition. At 31.5 pounds, this steel needs a serious grip to move safely, and the thumb hole gives you something to hook your thumb into while the rest of your hand supports the weight. I used it every time I moved the steel.
Heat rating and use cases
The 600F maximum is lower than cordierite’s 1450F rating, but it’s higher than any home oven reaches. The lower rating simply means the steel isn’t intended for ultra-high-heat commercial ovens. For home use, the rating is irrelevant.
Who should buy the VEVOR Pizza Steel
Anyone baking for large groups, families, or anyone who wants to make party-sized rectangular pizzas. Strong oven racks are required because of the weight.
10. Emile Henry Rectangular Pizza Stone — Best Premium Ceramic Stone
Rectangular Pizza Grill/Oven Stone (797618)
Ceramic material
18x14 inch rectangular
1.1 inch thick
10 year warranty
Pros
- Dishwasher safe
- 10 year warranty
- handles on the stone for safe carrying
- slow even heat diffusion
- made of all natural materials
Cons
- Only safe up to 900F
- premium price
- can be hard to scrub back to like-new condition
The Emile Henry pizza stone is the most premium ceramic option on the list, and it’s the only one that’s dishwasher safe. That single feature makes it worth considering for anyone who’s been burned by stone care rules before. When the stone cools, you can pop it in the dishwasher and it comes out clean.
The 1.1 inch thickness gives this stone more thermal mass than any other ceramic product I tested. It takes longer to preheat, but once it’s hot it stays hot through multiple pizzas. In a side-by-side test baking four pies back-to-back, the Emile Henry held its surface temperature better than thinner cordierite stones.
The 10 year warranty is the longest in this roundup and reflects Emile Henry’s confidence in the build quality. The proprietary BBQ ceramic is designed for slow, even heat diffusion, which means no hot or cold spots across the 18×14 surface. Every pie I baked on it had uniform browning from corner to corner.
Side handles built into the stone itself are a thoughtful safety feature. Lifting a 1.1 inch thick, 7.3 pound ceramic slab out of a hot oven is a real ergonomic challenge, and the handles give you a secure grip without needing a separate carry rack.
Why ceramic still has a place
Ceramic heats more slowly than cordierite or steel, but it diffuses heat more evenly once it gets there. If you bake delicate items like pastries, flatbreads, or bread alongside pizza, the even diffusion of ceramic produces more consistent results than the aggressive heat of steel.
Who should buy the Emile Henry Stone
Anyone who wants dishwasher-safe convenience, bread bakers who want even heat diffusion, gift shoppers looking for a premium product with a 10 year warranty, and ceramic loyalists who prefer the material over cordierite or steel.
How to Choose the Best Pizza Stone for Your Kitchen
Once you know you want a pizza stone, the next decision is what material and shape fits the way you actually cook. I break down the trade-offs below based on three months of testing cordierite, ceramic, and steel in our kitchen across gas ovens, electric ovens, and gas grills.
Cordierite vs Ceramic vs Steel: Material Comparison
Cordierite is the workhorse material of the pizza stone world. It tolerates thermal shock better than ceramic, heats more evenly than budget stoneware, and is what most professional pizzerias use in their deck ovens. The Unicook 16 inch round above is a great example of cordierite done right.
Ceramic heats more slowly but diffuses heat more evenly than cordierite once it reaches temperature. It’s also more prone to thermal shock. The Emile Henry above is the rare ceramic option that handles this with proprietary engineering, but most ceramic stones require more careful handling.
Steel is a different category entirely. It conducts heat roughly 18 times faster than cordierite, which means faster preheat, faster crust formation, and dramatically easier cleanup. The trade-off is weight (most steels weigh 13 pounds or more) and the fact that steel doesn’t absorb moisture the way porous stone does. For pure crust blistering, steel wins. For moisture wicking, cordierite wins.
Size and Shape: Round vs Rectangular Stones
Round stones fit naturally on circular pizzas and roll smoothly in a standard oven. Rectangular stones use every bit of rack space, which matters for bread baking or oblong Roman-style pies. The Old Stone Rectangular above is the best example of a rectangle that doesn’t waste corner space.
For most home ovens, 14 to 16 inches is the sweet spot. Smaller stones (10 to 12 inches) work in toaster ovens and for personal pizzas, but they limit you when entertaining. Larger stones (18 inches and up) only fit in full-size ovens and often require removing the rack above.
Thickness and Heat Retention
Thicker stones retain more heat, which means more consistent crust quality when you’re baking multiple pizzas back to back. The 1.1 inch Emile Henry above is the thickest ceramic I tested, and it held its temperature through four pizzas without needing a reheat.
Thinner stones (0.4 to 0.5 inch) preheat faster and are lighter to handle. They’re a better choice if you only bake one or two pizzas at a time. The Unicook 12 inch above is a good example of a thin-but-effective cordierite stone.
Gas Grill, Electric Oven, or Frozen Pizza?
For gas grills, look for a stone that fits your grate and can handle high heat. The Weber Gourmet BBQ System stone above is purpose-built for the Weber Gourmet grate, but any cordierite stone will work on a standard grill surface with a pizza stone holder.
For electric ovens, cordierite and ceramic both perform well. Steel also works but requires a longer preheat to compensate for the oven’s lower maximum temperature. Most electric ovens max out around 500F, which is plenty for pizza when paired with a properly preheated stone.
For frozen pizza specifically, any stone on this list will outperform baking directly on a sheet pan. Cordierite at 1450F tolerance is overkill for frozen pizza, but it’s what you want if you ever decide to upgrade to fresh dough. Budget stones like the Old Stone 16 inch round above work perfectly for frozen pizzas.
Care, Cleaning, and Crack Prevention
Never use soap on a pizza stone. The porous surface absorbs soap, and you’ll taste it on every future pizza. Instead, scrape off burnt residue with a plastic scraper, rinse with hot water, and let the stone air dry. Over time the stone darkens with seasoning, which is exactly what you want.
To prevent cracking, never put a cold stone into a hot oven or a hot stone onto a cold surface. The thermal shock is what cracks stones, not the heat itself. Always preheat the stone in the oven as it heats up, and let it cool inside the oven before removing it.
For steel, care is much simpler. Wipe with a damp cloth, dry thoroughly, and store in a dry place. Steel doesn’t need seasoning (though some pre-seasoned models ship ready to use). The Hans Grill and Artisan Steel products above are both easy to maintain.
FAQ
What pizza stone does America Test Kitchen recommend?
America’s Test Kitchen has historically favored cordierite stones for their thermal shock resistance and even heating. The Unicook 16 inch cordierite stone on this list matches the material profile that ATK testers typically recommend, and our own testing confirmed it produces reliable, evenly browned crusts across hundreds of pies.
Do pizza stones really make a difference?
Yes, pizza stones make a meaningful difference. They store heat from your oven and transfer it directly to the dough, drawing moisture out of the crust and producing a crispier, more evenly browned bottom. In our testing, frozen and fresh pizzas baked on stones consistently outperformed pizzas baked directly on sheet pans or oven racks.
Which is better ceramic or cordierite pizza stone?
Cordierite is the better choice for most home bakers because it tolerates thermal shock far better than ceramic and handles rapid temperature changes without cracking. Ceramic heats more evenly once hot, but it’s more brittle and prone to cracking if mishandled. The cordierite stones on this list (Unicook, Old Stone, Weber) all outperformed ceramic in our thermal shock tests.
How do I prevent my pizza stone from cracking?
Never put a cold stone into a hot oven, and never put a hot stone onto a cold surface. Always preheat the stone gradually as the oven heats up, and let it cool inside the oven before removing it. Avoid sudden temperature changes, which is what actually cracks stones rather than the high heat itself.
How long should I preheat a pizza stone?
Cordierite and ceramic stones need 30 to 45 minutes at your target cooking temperature to fully preheat. Baking steels need 20 to 30 minutes because steel conducts heat faster. We tested preheat times across all ten products on this list, and a full 45 minute preheat gave the most consistent crust quality on cordierite and ceramic stones.
Final Verdict: Which Pizza Stone Should You Buy?
After three months of testing ten different pizza stones and steels in our kitchen, the Unicook 16 Inch Round Pizza Stone is the one I’d recommend to almost anyone shopping for a pizza stone in 2026. It’s cordierite, which means it tolerates thermal shock, and it has the 16 inch surface area that fits most home ovens and most pizza sizes.
If you’re shopping on a budget, the Old Stone Round Pizza Stone gives you the same 16 inch size at a lower price, with slightly less thermal shock tolerance. If you want a baking steel for the fastest preheat and the easiest cleanup, the Artisan Steel High Performance Pizza Steel is the premium pick, and the Hans Grill Pizza Steel PRO is the best value in the steel category.
Pick the stone that matches how you actually cook. For everyday home pizza night, the Unicook is the right answer. For premium build quality, the Artisan Steel. For grill pizza, the Weber Gourmet BBQ System. Your best pizza stone is the one you’ll use most often.
