Not necessarily, but you want to get some heat into that area as well so I would at least build the vent arch the decorative arch can be done afterwards

Looks great you have got good symmetry on the last few courses.
IMO I wood put some insulation on first before you start the curing, I always suggest no flame just use what we call heat beads (briquettes) spread them out over the hearth and keep them going as long as you can I just did my oven for 14 hours straight I will do it another couple of times before I have the first small fire
Cheers Doug

Sweet I just have the keystone left to do. I finished the 9th, 10, 11, and 12th courses today. I did set up a plywood disc for the last course and i set all the brick waited 2hrs and pulled it off cleaned the loose mortar off the face but didnt want to wipe it down with a sponge because its still wet and I didnt want to disturb the brick so I still have some cleanup on the inside to do. The bricks are like 1/4" lower than the last course i could have made the form a little smaller than the opening so it fit right in there and not on the previous course. I guess I can grind it down with the grinder if i want later to make it smooth. Heres a few pics of my progress.Last edited by Chach; 06-03-2019, 02:27 AM.

Yes i shoved a few layers of rope in to lightly fill the void and the top half inch is just ash. No metal of any kind. You can buy ceramic roap from menards by the fireplace stuff.

It helps with heat retention for extended cooking. All i did was to put a thick pice of cardboard between the vent and oven and bevel the edge of the bricks to reduce the exposed area. Then filled the gap with ceramic rope then made some vermicreete to seal the outside and used a product called fiberfrax to seal the inside of the vent. Then some rope in the crack on the floor and let it fill with ash. Not hard to do.

Originally posted by UtahBeehiver View PostKinda up to you, if you want to tweak every last btu out of the oven and doing extended oven cooking over several days then thermal breaks are a good option, I did both. But if you are going to cook pizza and maybe something the next day then it may not be as big a factor. A well insulated door is a must and preferably not made of carbon steel, aluminum or high K value material. As Randy mention, thermal breaks are not difficult to install initially. Builder's choice.

Well I'm on the 9th course and I'm 3/4 of the way done with that and I figure I have 3 more courses to do and then the keystone. Pending on weather I may finish the dome this weekend but it seems to storm everyday lately.
With that being said I was thinking about thermal breaks..I have seen mixed reviews on the forum. Is it necessary? I understand the concept by having it you don't heat up the vent landing and outer arch and use fuel to get that hot and it also helps with heat wicking out. Just curious on opinions on this as this will be my next step. Thanks in advance

Congratulations on clearing the arch. That makes it easier from then on and speed increases. Just keep paying attention and you will be done in no time. It is looking very nice.
