Pizza fire

If your pizza is burning, it's normally one of two reasons. Your crust is not made for high heat like the hand made stuff at a Pizzeria. Or your set up is not correct in your XL.
Most common problem is people burning the bottom of the crust before the rest of the pizza is properly cooked. We will run with that for now.
Why does the bottom of your crust burn first? Because your pizza stone is hotter than the temp in the dome of your Egg. This happens if you are not using an indirect barrier, or a piece that is to small, between your fire and your pizza stone. Or because the indirect piece is spaced to far from your pizza stone. A large gap between the 2 cause the hot air to roll around the first indirect pice and directly into the bottom of your pizza stone. This heats your pizza stone to a much higher temp than your Egg temp in the dome and your crust burns. The higher the temp you try and cook your pizza the more critical your set up becomes. You only need a 2-3 inches between the 2 stones.
The photos below were pizzas cooked at very high heat with no crust burning.
The heat flows around the the first barrier, past the pizza stone and into the dome. Not a large gap for the heat to run into the bottom of the pizza cooking stone. I was using and old gas stove cooking grate as the spacer. There was a pizza on the stone in the lower 2 photos. Getting higher in the dome also works better for me. And NO, you don't need that much heat to cook a nice pizza. And if you try and photograph a flame ball, use a friends camera.lol
