I think the key to maintaining good floor heat is a flame licking most of the way across the dome at all times. Again, what Richard said!

I don't think hot coals does the trick, has to be flame. It bounces off the dome and charges the floor with heat. Coals do seem to work well for charring off those spilled ingredients.

The dome will go white at about 750 F, but I always shoot for something in the 900 range before letting the oven moderate. This guarantees that the floor will be hot enough.

A while back, I posted a few fire pics in the photo gallery, as have others with similar experience. Maybe have a look. There is one that shows what I call the "plasma" stage, where the very air seems on fire. That's what you're looking for.

Burn time is a question that seems almost individual to each and every oven. It's a matter of mass and insulation, plus wood type, plus beginning temp of the floor, plus fire size. Don't forget, you want to generate as much flame as possible.

Jim, you speak of plasma heat and photos in Gallery. Would you be so kind as to show the plasma photo here again? As for deep dish pizzas, how would one properly do this? It appears that frequent conversation is on thin pizzas.

Here's a photo of mine of what I think Jim is calling the plasma stage

Dutch, Acoma,

Dutch's pic says it well, although I'm adding mine here as well. I suspect that for deep dish pizza, like some breads, the floor temp should be a bit lower to assure a full bake of the crust. I'd bow to the pizza experts on that one, though.

Acoma,

Go to the Photo Gallery and look for my Crib Fire pics under Vent and Chimney. They show the beginning of a "frightening" fire.

Jim, J W, and Dutch, thank you for the photos. These help to establish what appears needed for longer sustained heat, especially on the cooking floor. Jim, I will go to the Gallery to see the pics you reference above. It makes sense to do deep dish at lower temps. I guess if you want a couple deep dishes at the same time, one might consider 650 degrees for 8 minutes? Someone can confirm this with experience to the deep dish.

Acoma.

Here are some more "plasma fire" pictures from my firing today.

The first one shows the starting fire, note some of the flames licking over the lintel and up the chimney...that is the part that makes the wife say oh !@#$!

The second picture is about 2 minutes later.

The third and fourth are about 20 minutes later. The fire has been pushed back into the oven.

(Finally got my camera fixed! Yea!)

I must say that you guys create flames that are quite impressive, plasma like. I look forward to my wife saying oh $#%^ too. Well, you guys can impress!! Drake, congrats on getting the camera fixed.

Acoma.

The flames going up the vent into the chimney definitely get some reactions from people...especially when the fire is located more in the back of the oven and the flames are shooting forward across the dome/vault...looks like you're looking into the pit of hades...wife got nervous and used the same expletives and warned me of a chimney fire!
