Hi i am building my first pizza oven and only want to build a small dome shape. what is the best type of stone to use to cook the pizza on? i know you use fire bricks to form the dome then insulation over that then is it clay? what sort of clay and insulation do i use? also what do i make the base for it all to sit on? I am going to copy a video from youtube which looks pretty basic, is this right?YouTube - building a wooden fired pizza oven, light construction.
