Frequently Asked Questions

No figure of 18 falls out of the published material constants. Conductivity is 29 to 38 times, volumetric heat capacity is 2.1 times, effusivity - the property that decides bottom crust - is 8.5 times, and diffusivity is 15.6 times. The claim appears to be a conductivity-shaped number being reused to describe stored energy, which is off by a factor of nine. The full comparison.

The stone, marginally. A 7.3 lb cordierite round reaches 95 percent of oven temperature in about 25 minutes; a 15 lb quarter-inch steel takes about 27. The bottleneck is mass rather than conduction, and the steel is heavier. Full table and derivation.

About 25 minutes past the point your oven says it is ready, for a typical 15 mm stone, and about 40 for a three-quarter-inch one. The beep is about the air, not the stone.

A quarter inch for almost everyone. Three eighths only if you bake several pizzas in sequence, because the extra mass buys recovery between bakes rather than anything visible on a single pizza. The thickness guide.

Yes, with a caveat. A stone is a large improvement over an oven rack or a sheet pan, and a modest step behind a steel - cordierite's thermal effusivity is about an eighth of carbon steel's, so the contact patch cools further when the base lands.

Almost always a temperature difference across the body rather than absolute heat: a cold stone put into a hot oven, or something cold or frozen placed onto a hot stone. Cordierite tolerates 1450 F and tolerates rapid gradients badly. The six causes.

No. Unglazed cordierite absorbs detergent and releases the smell and taste of it back into everything you bake for months. Scrape it dry, wipe with a barely damp cloth, and let it stain.

Wood to launch, thin metal to turn and retrieve. Raw dough releases from a porous wooden surface and welds itself to smooth metal within a minute or two; a baked base needs a thin edge that only metal can provide. Why.

Time, nearly always. Moisture from the base wets the flour underneath and turns it to paste. Dress fast, shake the peel every 20 seconds, and use semolina rather than plain flour.

About 386 g at standard thickness. Dough scales with area, not diameter, which is why a 16-inch pizza needs 78 percent more dough than a 12-inch one rather than 33 percent. The chart and the arithmetic.

As hot as it goes - 500 to 550 F for most - with the surface given long enough to actually get there. There is no domestic pizza style that benefits from a lower setting, other than thick pan and deep-dish.

For surfaces, if the emissivity setting matches the surface. That caveat matters: on ceramic a default 0.95 is close, but on seasoned steel - published emissivity 0.66 to 0.80 - the same instrument reads 40 to 83 F low. The arithmetic.

About 21 cents for a full hour on a 2.4 kW electric oven at the current US average residential rate. Extending a 15-minute preheat to an hour costs about 10 cents. Full derivation.

Not below about a dozen balls at a time. The dough box most guides recommend is 25 5/8 inches wide, which is wider than most domestic fridge shelves are deep. The comparison.

Only in a very hot oven. 00 is a milling grade optimized for 800 F, 90-second Neapolitan bakes. In a 550 F domestic oven it browns too slowly, and bread flour usually gives a better result.

No, and we say so on every page. There is no test kitchen and no owned equipment here. What we do instead is compile published specifications with a citation on each one, compute the thermal numbers from published material constants and show the working, and read the makers' own manuals. The full method.

Because a price typed into a page becomes a false statement the moment it changes. Prices render only from a live data layer with a 48-hour freshness gate, and at present that layer holds no data - so every buy button reads "Check price" instead of showing a number we could not stand behind.

Affiliate commission, and nothing else. You pay the same price; the commission comes from the retailer's margin. We accept no paid placement, no sponsored content and no free products. The full disclosure.

No. Ranking follows the weighted criteria published in the methodology, and the site regularly recommends the cheaper option, the option that earns us less, or no purchase at all - there are pages here whose honest conclusion is "preheat for longer and buy nothing".

Because we hold no verified image of that specific model. Rather than leave a blank space we show a licensed photograph of the product type, and both the caption and the alt text say exactly that. Nothing is presented as a picture of a particular unit.
