pilling up stone, no heat improvement, why not?
So I have this pizza oven. I use it for bread baking. It came with a 1,5cm thick stone (50x60cm). I tried pilling up an extra 1,5cm stone over half of the original stone.
After a good 1h of pre-heating at 300°C (IR thermometer gave a 290°C for both stones).
I baked 2 pizzas, one on the 1,5cm area the other on the 3cm area.
- no visual differences
- no cooking time differences
- even more strange, after baking both stones read 200°C with IR thermometer (so a drop of approx. 100°C).
So it is as if pilling up stone changed nothing... Any idea why not?
