To anyone who has never tried a pizza stone, try it, The difference is astonishing. Whether its a proper stone, cutting board, floor tile, or just a heavy thick piece of metal.
A proper pizza stone works brilliantly, they just don't seem to last long and are fragile at best.
Whatever you use, make sure you put yr oven on the highest setting it'll do (assuming its a household oven), anything around 200-230 deg C, or even 250 if yr lucky enough to have an oven that'll do that high. Put the stone/metal plate in, and leave it for at least an hour to get up to temperature and let the stone heat up.
I use a flat baking sheet to put my pizzas in the oven instead of a peel. But make sure you use either corn flour (not corn starch), or semolina to dust the surface of the 'peel', bottom of the pizza. The course ground stuff works like little ball bearings and the pizza will come off the peel much easier. And You wont get clumps of white 'dough' / flour on the base if yr pizza.
