Hi,
Greetings! We just finished a Pompeii oven in Wisconsin. It's been in the 30's at night and 40/50's in the day. The oven has rested about 2 weeks, and we went through the curing fire schedule over the past week. Our fire today was about 1 1/2-2 hours and we were just about 700 degrees, but were having trouble holding that temp without adding a lot more wood. We didn't ever seem the black to white changes on the dome top. How was our fire too small? Should it be roaring? After looking at some of the photos, our dome is pretty high (but built to the plan) The pizza was good tasting... after I botched the peel and most of the pizza was upside down! Still great, and not too worried. Just need some tips from the pros. Thanks!

Our fire today was about 1 1/2-2 hours

Even though you have completed the curing schedule, doesnt mean you have allllll the moisture out,, give it another week or two with regular pizza fires and you will see the difference,, also make sure you are using good seasoned wood... wet wood will take a lot longer to heat an oven than seasoned hardwood...

Oh, and that thing you did to the pizza we call that the "accidental calzone" when it sticks to the peel and rolls over..... all part of the learning process..

Cheers

Describe your insulation. It's really hard to give advice without understanding the insulation.

Should it be roaring?

Yes, - almost. Truth is, you can always go from black to white regardless of how well your oven is insulated. It is just a matter of the skin temperature on the inner surface. Just throw in enough wood for a big fire. The trouble with too low insulation is that you are not able to hold the temperature when your fire cease.

Thanks so much for all of your advice. Things are going much better. Had a great fire with smaller, drier pieces of wood. In just under 2 hours, the black to white ash was complete. The oven was still at about 125 today with the door open all night and the outside temp dipping into the 30's. The insulation is the ceramic blanket over the fire brick/mortar and about 17 bags of vermiculite, with a cinder block wall, and poured cement roof. The mason who built it for us made sure it was well insulated. The floor is fire brick over the insulated cement.

We loved the "accidental calzone" comment! Our pizzas were also much better (or we were better!). Thanks again!

Great news. Too often contractors leave out the insulation. Yours sounds like they new what they were doing. Although I haven't had enough fires to experience it yet, other members of the forum have noticed increased efficiency after a dozen or so fires. We apparently still need to drive some of the moisture out of the oven. I haven't had an accidental calzone yet, but my early pizzas ended up with most of the toppings on one side. And I've had some very out of round pizzas that stuck to the peel as I tried to slide the pizza into the oven. I'm getting better at that, too.

Yep, you have to get rid of all the moisture. More firings will fix that.

It sounds like your oven is very well insulated.

Enjoy!

And don't be afraid to really get a good fire roaring...if I don't see flame flying up the chimney...I throw in another log or two!
