Don't be in a rush to finish. After you do the vermicrete/perlcrete (it is easier to do it in layers about 2" thick at a time) let it dry for a week, then do your curing fires, then the stucco. Good luck, you're nearly there.

I'm just wondering if I will need a form for the soldier wall or will the perlcrete stick to a vertical wall?

I think you will find it will stay ok. You might make the base a little wider to give it slightly more support. It is a weird mixture and you'll think "this'll never harden up enough", but it does. Do two layers with some drying time in between. Tap the outer surface with the flat of your trowel. The other main trick is to leave a flat top on the wall you are buiding so that the next level has something to sit on. Also get the right amount of water in the mix. 10:1:3 vermiculite,cement,water.

as david says im sure it will stay, If you have a problem a very temporary form will probably help, ie: a piece of aluminum, some stacked up bricks etc.... it is definitely weird stuff, think of building a wall out of thick oatmeal
cheers

Fact...stucco is not sold in my town.

First Question...If I add liquid acrylic fortifier to the perlcrete and then a coat of oil based exterior paint after it has been fired cured, Will it be okay? (ie: waterproofed and resistant tu occasional bumps and dings?

Second Question...Is there a product that is an alternative to stucco?

Joey,

Quickrete has a fiber reinforced product that I am about to use. I may stucco over it, but I just may leave it as my finish coat. I am also gonna wire my dome..... I think its like $15.00 a bag, and has polyethene or pvc shavings to reinforce the cement.

You are in Louisana...You gotta have stucco somewhere... HD and Lowes....

Love the oven! I wanna try to build a portable too.

Rick

Thanks,
both of those guys (HD & LOWES) do not carry stucco, they mumbled something about the humidity blah...blah...blah...

When you say you're gonna wire it, do you mean chicken wire?
