First course

[Mike D]

I know this sounds lame, but I would pull off what you have now and start it over again. Your not that far into the dome. And the amount of time you have already put into it (the stand an foundation), and the amount of time you have left would be a shame if you were to build an oven that you knew to be flawed.
-The insulation under all the bricks serves as a heat break. You soldiers will be moving your heat into your slab not back up into the dome.

I admire your views and ideas about building ovens. You're a great help. Thanks for the info. Good job.

So what did you decide to do in the end Omaharosario?

I think we are going to cut out 2" of the fire brick soldier course and the stuff all the insulation we can fit in and around the fire brick soldier course. then all will be floating on insulation. does this sound like a comparable change to fix things?

Oma,

I may have jumped the gun on my first post (using a smart phone, not much detail with the pic's) You have 50% of the soldier course above the floor. It's hard to believe that the brick can wick that much heat to ruin your build. It's does conduct heat but it's not like it's a solid bar of copper. It's not an ideal situation but may not be a disaster either. JMT

I tend to think like Les (scary, huh ) - 50% is better than 100% and most of us are just trying to make a few pizzas in the evening and don't care too much about retaining heat for baking bread the next morning.

If you fit into this category - I think you'll burn a bit more wood but you'll be fine with the changes you are making.

Can't wait to see more pics!!

Just pull them up and relay them. This might tale less time and trouble.

I am a little worried about not being able to use the FB after we pull them off. I am thinking they are going to be all gumed up with mortar?

When I pulled my soldiers apart most of the mortar came off easily. The stubborn pieces were easily removed with an angle grinder.
