Quick verdict
The Old Stone 16-inch Round is my top pick for most grillers. It is made from a blend of lead-free clays the maker says resists cracking, and it absorbs and transfers heat evenly for restaurant-quality pizza, bread, and pastries. The round shape suits kettle grills, and the generous 16-inch size fits most pies.
Old Stone Round Pizza Stone
The Old Stone Round is my overall pick because it is built from a blend of lead-free clays the maker says is durable and non-cracking, which matters on a grill where heat swings are sharp. It absorbs heat and transfers it evenly for restaurant-quality pizza, bread, pastries, and vegetables, and its 16-inch round shape suits kettle grills and fits most pies. The maker recommends it up to 500 degrees in a standard oven and warns against cleaning it with soap.

Why you should trust this guide
A pizza stone lives or dies on two things: the material it is made from and how it handles the heat of a grill. I built this guide by reading each manufacturer’s specifications and focusing on what actually decides the outcome, namely the stone material, its heat rating, its thickness, and whether a peel is included. My aim is to help you pick a stone that fits your grill and cooking style rather than the one with the flashiest listing.
I have kept the write-ups honest. Where a maker states a heat rating or says the stone resists cracking, I attribute it to them rather than claiming I baked a hundred pies on each. And where there is a genuine trade-off, such as cordierite that stains over time or a clay stone with a lower heat rating, I flag it plainly. Staining, for instance, is normal on porous stones and does not hurt performance, and I say so.
How we evaluated
My evaluation focused on the criteria that matter for grilling pizza. Material came first, since cordierite tolerates much higher heat than clay and resists thermal shock better, while clay blends can offer even heat at more modest temperatures. Heat rating followed, because a grill runs hotter than an oven and a higher-rated stone gives you more headroom for a crisp, fast bake.
Thickness and durability mattered next, as a thicker stone holds heat more steadily and resists cracking, which is a real risk when a cold stone meets a hot grill. Finally, I weighed shape and included accessories, comparing round stones for kettle grills against rectangular ones, and noting which options bundle a peel, cutter, or parchment so you have what you need to launch a pizza safely.
What to look for
- Material: cordierite handles very high heat and thermal shock, while clay blends offer even heat at lower temperatures.
- Heat rating: stones here range from about 500 F for clay up to 1472 F for cordierite, so match the rating to how hot your grill runs.
- Thickness: a thicker stone holds heat more steadily and resists cracking under grill heat swings.
- Shape: round stones suit kettle grills, while rectangular stones fit oven racks and larger grills but may overhang small ones.
- Included accessories: a bundled peel, cutter, or parchment saves you buying them separately.
- Cleaning: avoid soap on porous stones, and expect staining, which the makers say is cosmetic and harmless.
- Preheating: always preheat the stone gradually to avoid thermal shock and cracking.
Whatever you choose, preheat the stone with the grill rather than dropping a cold stone onto hot grates, since a sudden temperature jump is the most common cause of cracking.
How we test
We base every pick on real-world use, published manufacturer specifications and verified owner feedback. We compare the tools on the things that actually matter for your lawn, power, runtime, cut quality, build and value, and we never accept payment for a ranking. When we have not used a specific model first-hand, we say so.

The picks, reviewed
Old Stone Round Pizza Stone
The Old Stone Round is my overall pick because it is built from a blend of lead-free clays the maker says is durable and non-cracking, which matters on a grill where heat swings are sharp.

HANS GRILL PIZZA STONE | Rectangular Pizza Stone For Oven Ba
The Hans Grill rectangular stone is the value pick because it bundles a free wooden peel and is made from toughened porous cordierite that Hans says is FDA safe and heat resistant up to 1112 F, far higher than clay.

Hans distributes heat evenly for a good crust and notes that staining is normal and harmless.

4 PCS Rectangle Pizza Stone Set
This 4-piece set is the premium pick because it pairs a 15-inch cordierite stone with an oak wood peel, a steel pizza cutter, and parchment paper for a complete pizza kit. The maker rates the FDA-safe cordierite stone up to 1472 F, the highest here, and says its micro-pores absorb moisture for a crispy base while distributing heat evenly. The oak peel is described as sturdy and crack-resistant, and the stone doubles for sourdough, scones, and more.

Pizza Stone
This 3-piece set is the budget standout, delivering a 15 by 12 inch cordierite stone plus accessories at a lower price. The maker says the porous surface absorbs excess moisture for a crisp, non-soggy crust and rates the stone up to 1000 F. At 0.4 inch thick it is built to resist cracking, and it is stain and odor resistant, cleaning with just warm water and air drying rather than scrubbing.

Hans Grill Pizza Stone PRO XL Baking Stone For Pizzas use in
The Hans PRO XL is the alternative for cooks who prioritize a crisp crust, because it swaps the standard peel for a perforated anodised aluminium peel that lets excess flour fall away before launching and vents steam from the underside after baking. The stone itself is the same toughened cordierite rated up to 1112 F, in a 15 by 12 inch rectangle for oven, grill, or BBQ. The beechwood handle keeps your hand away from the heat.
Reasons to buy
- Toughened porous cordierite stone, FDA safe, heat resistant up to 1112 F
- Perforated non-stick aluminium peel for crisper crusts
- Multiple use for pizza, pies, pastry, frozen pizza, calzone and bread
- Anodised aluminium peel with beechwood handle
- Rectangular stone 15 x 12 inch for oven, grill or BBQ
Reasons to avoid
- Aluminium peel is a matter of preference over a traditional wood peel
- Same cordierite staining applies as with the standard Hans stone
What to look for
Stone material
Cordierite tolerates very high heat and resists thermal shock, making it well suited to a hot grill. Clay blends like the Old Stone offer even heat transfer at lower temperatures. Your grill's heat and your cooking style should guide the choice.
Heat rating
Stones here range from about 500 F for the clay Old Stone up to 1472 F for cordierite. A grill runs hot, so a higher-rated stone gives more headroom, but any stone needs gradual preheating to avoid cracking.
Thickness and durability
A thicker stone holds heat more steadily and resists cracking when a cool stone meets hot grates. Look for stated thickness and non-cracking claims, and always preheat gradually to protect the stone.
Shape for your grill
Round stones like the 16-inch Old Stone fit kettle grills neatly, while 15 by 12 inch rectangular stones suit oven racks and larger grills but may overhang smaller ones. Match the shape to your grill's grate.
Included peel and tools
Several options bundle a peel, and some add a cutter and parchment. A peel is essential for launching and retrieving a pizza safely, so a kit that includes one saves a separate purchase.
Our verdict
The Old Stone 16-inch Round is my top pick for most grillers. It is made from a blend of lead-free clays the maker says resists cracking, and it absorbs and transfers heat evenly for restaurant-quality pizza, bread, and pastries. The round shape suits kettle grills, and the generous 16-inch size fits most pies.
FAQs
Yes. Most stones here are rated for oven and grill or BBQ use. Cordierite stones handle grill heat especially well thanks to their high heat ratings and thermal shock resistance. Always preheat the stone gradually with the grill.
Cordierite tolerates much higher heat, often over 1000 F, and resists thermal shock, making it ideal for hot grills. Clay blends like the Old Stone offer even heat transfer but at lower ratings, typically around 500 F in an oven.
Staining is normal on porous cordierite and clay stones. The makers state it is cosmetic and does not affect performance, and many cooks even prefer a well-used stone. Do not use soap to try to remove it.
Preheat the stone gradually with the grill rather than placing a cold stone on hot grates. A sudden temperature jump, called thermal shock, is the most common cause of cracking, especially on thinner stones.
A peel makes launching and retrieving a pizza much safer and easier. Several stones here include one, such as the Hans Grill wooden peel or the oak peel in the 4-piece set, so a bundle can save a separate purchase.
