 Re: pumice stone vs vermiculite; clay vs brick
No help here. I'd expect that pumice would work OK, but if I could find ceramic board or vermiculite, I'd do that.
The less insulation you have under the floor, the faster the oven floor will cool, or the harder it will be to get hot, which will likely result in lower temps to cook your pizza on.
