Baking steel vs pizza stone – how the difference will be measured
Steel conducts heat better than stone – but how much does it show in a home oven? Test plan: surface temperature, recovery and base colour over four pizzas.

Results Planned
The experiment is planned. We will publish the measurements as soon as the runs are done — even if they contradict what we expected.
Method
Status: planned. This test has not been done yet. This page describes the set-up so that the method can be scrutinised before any results exist. Figures will be added here once the runs have been done and repeated – even if they contradict the hypothesis.
The question
Steel or stone in a home oven? It’s one of the most common equipment questions, and most answers rely on material data rather than readings from an ordinary home oven.
What we already know
Established physics: steel has a much higher thermal conductivity than ceramic stone and gives up its heat faster. That points to a faster-baked base – but also to the steel possibly losing more heat per pizza.
Hypothesis
The steel gives a faster, darker base on the first pizza. The difference between the first and the fourth pizza is larger for a thinner surface than for a thicker one.
How the test will be run
Same dough, same toppings, same oven. Each surface is preheated for an hour, then four pizzas are baked in a row, with the surface temperature read with an infrared thermometer before every launch. The bases are photographed against a grey card so the colour can be compared.
Limitations
One oven model and one thickness per material. The result says nothing about steel and stone in other thicknesses.
Background: baking steel, pizza stone, pizza in a home oven and how we test. All tests are listed under Tested.
