Search your local garden center for terra cotta tile. Choose an unglazed plain tile that measures about 14 inches square.
Remove any stickers or price tags from the tile. Rinse the tile off in clear water briefly then brush the tile surface with a vegetable brush. Place the tile on a dish drainer to air-dry completely.
Move one oven rack to the lowest shelf position. Do this while the oven is completely cold.
Place the pizza stone block in the center of the bottom oven rack. Make sure air can circulate around all four sides of the stone.
Turn your oven on and preheat it for pizza baking. Slide the raw pizza onto the hot stone when the oven indicator light shows the oven is heated to the desired temperature. Leave the stone in the oven after the pizza is done.
