Pizza stones are a nice way to get around the drawbacks of modern ovens. The very old ones don't seem to need one. I've been baking bread and pizzas for years at my parents-in-law's cabin in Sweden in a very old oven that heats the whole place at the same time - and the result is excellent, almost every time. Now, apart from the stone, key factors in making a pizza are: Make your own dough, with very little yeast, from 5/6 pizza flour and 1/6 pasta flour plus water and salt. Make sure it is rather sticky, let it grow slowly (at least 8 hours) in a bowl in a cool place. It should be covered with a damp cloth and a lid. When it has increased to double size, pour a thin layer of pasta flour on your working table, turn the dough carefully (in one piece) onto the flour, cover it with more flour and work it into the desired shape, starting from the center. The oven should be HOT! Apart from this, of course it should not be covered with too much filling. If you prefer to make small breads, cut the dough into smaller pieces. If you're not careful, some of the air will be squeezed out, and you will then have to let them rest for a few hours. Covered again, of course. This is as close to the classical method of bread-baking as you can get in our modern world. There is one drawback, though: Once you have mastered it, you will HATE most other kinds of bread, just like my family do, and you will have to bake and bake and bake and....
