I use a 15" cast iron pizza pan. I have a regular one and a deep dish one. I love them. I get the grill or oven as hot as it will go. 500 in the oven and a lil higher in the tbe or srg. They are well seasoned and only take about 15 minutes to cook. I do not wash them..only use hot water to clean them. Pizza slides right off, and I do not preheat them. Pam
