The only cracks I have are the ones I pre-engineered in the back and front of the oven. I fired my vault the next morning after laying up and every I time worked on it after, since it was cold out.
A crack is a crack - I don't think they are a problem unless you are a plumber...

Jim, I didn't bother with curing. I am fortunate enough to live in an area that in mid-summer, it wouldn't change a thing (I had very little mortar to cure anyways).
If your oven started to clean, go for it next time. Taking your time curing is not a guaranty that you will not get cracks. I do not believe that any one that uses mortar doesn't have some crack(s)
well i have been doing curing fires over the last week . the one today got the back and side walls to 550 , the hearth to 400 and the dome to 750 . so is it time , after the oven cools down , to build a full on scary fire ? What temps should i be looking for? thanks.
Let it snow , I am ready . That was the big push for me to get everything done to the point that it was weatherproof . I can still work on it as time and weather permits ( as you can see it still needs a ton of work ) but I dont have to worry about things getting wet or snowed on now .The roof jack for the chimney is at the fabricators now and should be done tomorrow . Most of the remaining work will probably be done next spring after worry of freezing , but I can start learning how to cook on this contraption soon !!
Got all the holes filled in the structure so now it was time to insulate . I put in 60 cubic feet of perlite ( 10 bags ) and this gave me , at the minimum insulation point 8 1/2 inches and at the maximum point 11 inches . I think that will work !!
here are a few more pics of the outside if anyone is interested.
Great looking oven, and congratulations on the curing fires! I am right there with you at that stage. Also, for every reply, there are at least a hundred others who are very interested in your progress .
Al the front arch is on its own platform . The whole front ( red bricks ) at this point is seperated from the hearth . The only portion that I am thinking will be touching will be when I start the chimney . I have not seen a way to isolate that part yet . So what do you think about the perlcrete or is there something better that is readily available ? Thanks.
