This silicone mat is very large , it is large enough to cover an entire oven rack ! It cooks in heat temperatures up to 480° . I love using this to bake cookies on because they turn out perfectly and never burn ! This is non-stick . You don’t put this one in the dishwasher you hand wipe it down . It is super easy to clean . There are measurements of all different sorts on the map that I find extremely helpful when I am cooking or measuring for baking !
