The stone is what turns any oven into a pizza machine: cordierite stores heat and dumps it into the base, giving the crunch a tray can never match.
The secret to a crisp base isn't the cheese or the whole oven, it's the stone. Ooni's cordierite stores a huge amount of heat and transfers it to the dough the moment the pizza lands, creating that golden, crunchy, bubbled floor that tells a pizzeria pie from a soft tray one.
Against other stones, cordierite stands out for taking thermal shock: it withstands the abrupt temperature swings of a pizza oven without cracking easily, which is exactly where many cheap stones fail. It's porous, so it draws moisture out of the dough and leaves it drier and crisper underneath.
It works as a replacement or upgrade for Ooni ovens, but it also transforms a regular home oven, a grill or a kamado: preheat it well and any of them bakes bread and pizza far above its usual level. The key is always preheat time: the stone is slow to charge, but then it doesn't forgive.
The accessory that changes the result most per euro spent. If you buy only one thing for your pizza, make it a stone. An emphatic Pick.

FAQ
Does it work in my kamado or home oven?
Yes. Cordierite works in home ovens, grills and kamados, as well as a replacement or upgrade for Ooni ovens. It just needs a good preheat.
How long should I preheat it?
It depends on the oven, but always longer than you think: the stone is slow to load with heat. In a pizza oven, let it reach full temperature before launching.
Why cordierite and not another stone?
Cordierite handles the thermal shock of pizza ovens better, so it cracks less than many cheap stones subjected to abrupt heat swings.
How do I clean it?
Only with a scraper or dry brush once cool; never with soap or in the dishwasher, because the porous stone would soak up detergent. Dark stains are normal.
Do stains mean it's ruined?
No. Use marks are cosmetic and don't affect performance; a seasoned stone bakes just as well.
