These are great for cooking pizza and flans. cooling food doesn’t ‘sweat’ and go soggy or cause rust on the surface as with a metal tray . The crust separates easily from the porous  surface and the terracotta holds the heat much longer than a metal baking tray. My design has sides of various depths, a decorated rim for easy handling and attractive serving , and a turned base with 3 ‘feet’ to make them lighter and avoid thermal shock. I have a range of sizes from dinner plate size up to 38 cm.
