This how to season a pizza stone guide covers exactly what you need to know, based on real use.
You’ll see advice online saying you should season a pizza stone with oil before first use. This is incorrect and will damage your stone. Pizza stones are made from cordierite or other porous ceramic materials — they should never be oiled. Here is what you actually need to know about pizza stone care, from first use through to long-term maintenance.
Do You Need to Season a Pizza Stone?
No. Unlike cast iron, a pizza stone does not benefit from seasoning with oil. Cordierite pizza stones are porous — oil applied to the surface will absorb into the stone, heat up during cooking, and produce smoke and unpleasant flavours. It can also cause the stone to discolour unevenly and become sticky in patches. Never oil a pizza stone.
The “seasoning” a pizza stone acquires naturally is simply the accumulation of flour, semolina, and carbonised food residue from repeated use. This creates a naturally non-stick, dark patina over time. You don’t need to do anything to create it — just use the stone regularly and it develops on its own.
How to Prepare a New Pizza Stone (First Use)
Before first use, place the stone in your oven or pizza oven and heat it slowly to cooking temperature. A gradual heat-up on first use reduces the risk of thermal shock on a brand new stone — take 15–20 minutes to reach full temperature rather than cranking the heat immediately. Don’t add water, don’t add oil — just heat it empty for the first session before cooking anything on it.
After the first empty heat cycle, your stone is ready to cook on. That’s the full extent of “seasoning” required.
Cleaning a Pizza Stone
- Never use soap or detergent — the porous stone absorbs soap and you’ll taste it in your next pizza
- Never submerge in water — saturating the stone then heating it rapidly can cause cracking
- Scrape off residue when cool — use a stiff brush or plastic scraper to remove stuck-on food after the stone has cooled completely
- Let the oven do the work — burnt residue will carbonise and turn to ash at pizza oven temperatures; after several cooks, most residue burns off naturally
- For stubborn stains — a damp cloth on a cool stone and a stiff brush is all you need; no cleaning products required
Different Stone Materials
Cordierite is the most common material in pizza oven stones. It has excellent thermal shock resistance, handles the temperature cycles of a pizza oven well, and is relatively affordable. Most Ooni and Gozney replacement stones are cordierite.
Fibrament is a denser cordierite composite used in some higher-end stones. It retains heat slightly longer and has a more consistent surface.
Biscotto di Sorrento (Neapolitan clay stone) is used in traditional wood-fired ovens. It’s highly porous, absorbs moisture from the dough for a crisper base, and is preferred by Neapolitan pizzerias. More fragile than cordierite and not suitable for portable pizza ovens due to its weight and brittleness.
Pizza steel is an alternative to stone — a thick steel plate that conducts heat more efficiently but doesn’t have the same moisture-absorption properties. Better for home ovens than dedicated pizza ovens, where the stone is already built-in.
Why Is My Pizza Stone Discoloured?
Discolouration is completely normal and expected. A well-used pizza stone turns dark brown or black in patches — this is the natural patina from carbonised flour and food residue. It does not affect cooking performance and does not need to be removed. A dark, well-used stone is a good stone; don’t try to clean it back to white.
Preventing Cracks
The main cause of pizza stone cracking is thermal shock — rapid temperature change. Never put a cold stone into a very hot oven, and never pour water onto a hot stone. Always heat the stone gradually with the oven from cold. If a crack appears, the stone can often still be used — the two pieces cook normally — but handle it carefully. Hairline cracks don’t affect performance; a stone that’s broken into multiple pieces should be replaced.
