I recommend using a baking stone or baking steel for cooking your pizza. Preheat your steel in the oven at 550ºF or as high as your oven will go for at least 45 minutes. You want the sucker hot! Real Napolitano wood fired oven pizza cooks in 90 seconds so the hotter you can make your oven the better. Use an additional stone if you have an extra to create even more heat above your pizza while it cooks. If you like charred crust place your stone in the upper level of your oven before preheating, and then when your pizza is is just cooked though (no longer then 5 minutes if your temperature is right) switch your oven to broil and let the bubbles char for 30-60 seconds.
