Ok, we read about the grape juice. Now what about the beer? Perspiring minds want to know! :-D

I brought several beers, but the only two I specifically wanted to try together were Shiner Ruby Red and the Margarita, and the Real Ale Rio Blanco Pale Ale for the Mushroom pie.

Gene, after puzzling out Craig's oven and talking to Bill about some plans he purchased, I think this is how Craig's is built and is able to withstand the thrust of such a flat dome, and it also explains the odd way his first course is positioned (it is not a soldier course, it is called a sailor course when it is laid vertically, wide side out).

Tom would you pour the refractory, lay the sailor inside of that and then build the dome? -or- in some other order?
That 15" measurement really has me turned on. ;D
I guess the dome butts up against the sailor course?

No, you would lay the sailor, then form the outside and place the concrete. You want 100% contact and bond at that point.  The dome rests against the trimmed sailor.

I am still debating, but I think it would work better, and after using Craig's, the door height doesn't bother me anymore (9x17).

Could we use the red bricks for the sailor ?

What is your plan for thermal expansion Tom?  I used a very similar method on my build and thermal expansion destroyed the stucco in no time.  This past weekend I ripped it all apart down to the brick and wrapped it with a layer of ceramic fiber(which I hate using due to health concerns).  Now I've got to redo the outer layers and Get her tiled and done.

The inner inch of perlcrete insulation will be almost loose fill, I am assuming that will have enough give for expansion.  How about alternating red and yellow ones?

Also, I do not think Acunto or any other Neapolitan oven maker use any major structural form of buttress.  I've seen pretty in depth Acunto build photos in the past that don't so it.  I can't find them now but did find some that seem to support my claim.

Here you see the Sailor course in place with a form behind it:

And here you see a picture where that form appears to have been filled.  The material behind the sailor course looks to be the same insulating mix used to cover the rest of the oven as detailed in the pictures I can't currently find

Yes, I agree that is the way they do it, but also after observing Craig's oven I came to several other conclusions.  First, the material they use for insulating is not nearly as good as perlite (the oven was too hot to touch on Sunday), but it is much more dense, they use the insulating material AS the buttress along with the exterior layer of stucco which by my estimation is a good inch (thump test), and is not reinforced by wire (looking in the cracks of the stucco).

That is why I planned to use a belt of refractory concrete (non insulating).  With the brick sailored, it will maintain the planned 4-1/2" of thermal mass, and will NOT rely on the insulation/stucco as a buttress.


How did you apply the perlcrete?

Jeff, that is a soldier course, is it not as strong as a sailor? Also, that pic , to me ,shows the outside form yet still using the soldier for the inside support/buttress,no?

Actually, I said that wrong.  They use wire, but it is 4x4 heavy gauge wire, not expanded metal lath.

Soldier is stronger than sailor, neither is strong as standard coursing.
