While it might be tempting to use an old aluminum foil facing as a pizza stone, it's not recommended. A proper pizza stone is made of materials like cordierite or ceramic, which can retain heat well and provide an even cooking surface. Aluminum foil conducts heat quickly and unevenly, which can lead to an unevenly baked crust and may even cause the foil to warp or melt. Instead, invest in a real pizza stone for the best results in baking pizza crusts.
