Ok, so I can actually light a small fire one day and a few days later start again and slowly buid it up until I fell certain that the moister is out then build it up to the 800 deg C. Thanks for the help , just a little scared to scew things up after all the hard work, hate to see it fall apart by doing something stupid.

I am still in the process of starting the curing on mine and as you see I too have many questions but have done a lot more re search and the way I see it be sure the oven is dry and if you have any dought then I would start with a small fire to get the oven warmrd up then when you feel it has dryed then bring on the wood. I live in Subury Ont Canada where the temps get as low as -30 deg C and evan colder, I would'nt start the party on those days but -10 or so I just may take my time and get the oven going.

James etal, just started my curing process of a 2GCasa100. I'm a little confused as Amanda at Forno Bravo told me I need to build a fire for 6-8 hours a day! Who has time to do that? I've been building small fires and keeping them going for about 2-3 hrs at a time. I'm building them fairly "slow" so it will likely take me more than a week to get to 800 F (measured at the dome). I've gotten the dome temp as high as 450 F but one really has to stay vigilant to keep it going with a steady temp.

I'm using smaller diameter sticks of hardwood, should I step it up to 1 - 1-1/2" pieces now as I start getting those bigger fires? Was so windy yesterday I had trouble keeping a descent fire going. Thx

Hi George, on the sixth curing fire I decided to take the approch of getting the fire to 700 or so and I kept feeding the wood to maintain the temp and it seemed to work well. For the first time I seen some smoke come out the dome and I did see a little steam as it was also a little out but after the fire the next day all loked great on the inside. I cove the couple of spots where the smoke was coming from. I will let the mortar cure for a week then fire it up again slowly when do you think I should start the big scary one. the inside did clear pretty much on the last firing

That's Amore, I would light up several more progressively larger dome clearing fires before lighting up the big one. Have you done any cooking, like roasts, during these curing fires?

No I have not cooked anything yet. So If I here you right, I should light up slowly again and keep them going for as long as I can. Sorry for all the questions I have done the research but I just don't want to mess up after all the hard work. It is just a little harder now with work kids homework and it getting dark at 5:00 but the weekends are mine so any direction would be great. Thanks for your response

If you saw steam coming out on your last firing I would still stay at the same firing intensity for several more days before going all out.

That sounds good, better to be on the safe side. The oven did clear the top 2/3's and I think it is well on its way to being dry so whats a few more fires. Thanks I hope to post some more updated pics. Thanks George

Just looking for a little reassurance that I'm on the right track here with my casa2g90

I let it sit for about 1.5 weeks after mortaring the joins and then started the curing fires.

Day 1 was for about 5 hours at ~130 C (~266 F) before closing the door to retain heat.
Day 2 was for about 12 hours at ~150 C (~300 F) before closing the door to retain heat
Day 3 was for about 10 hours at ~180 C (~350 F) before closing the door to retain heat
Day 4 was for about 5 hours at ~200 C (~400 F) before closing the door to retain heat
Day 5 (today, oven was still 160 - 170 C at the top of the dome first thing this morning) will be about 7 hours at ~230 C (~450 F) before closing the door to retain heat.

Tomorrow I will take it up to 260 (~500 F) for about 4 hours, before closing the door to retain heat. According to the current instructions that should be good enough, but it seems like a big jump to go to pizza temp from that?

I do have Thursday and Friday off, so I could run at least 8 hours each day with higher temps, perhaps 300 C (~570 F) and 350 C (~660 F). Looking to cook pizza's on saturday for the fiancee's bday.

I've been measuring from the very top of the dome ceiling using an infrared thermometer. My concern is that the floor is quite a bit cooler so I am not sure if I have been going about it the right way, and if I should have been basing my temperatures on the floor or wall (or air temp using a typical thermometer. Unfortunately, there is no thermometer in the door of my casa?). Floor was about 130 C a few hours ago (dome 230 C).

I've been using clean burning, non self igniting heat beats for the process, but am starting to add some small bits of wood. The first burn I did not have any insulation on, but every burn since has been insulated.

General advice / guideance anyone?
