The gauge on my Opal reaches 500 degrees. I don't know the particulars of the application but I wonder if seared fiberglass batting would be sufficient as an insulator.

I appreciate your advice but I've been able to source some verm and by all reports it's one of the best mediums you can use. Its for the outside of dome both top and bottom.
There are some pretty good formulas to use for calculating thermal mass and how it applies to heating, retaining and insulating.
Nutshell plan. I have base slab of concrete bout 100 mm Directly under oven there's going to be 80mm of verm underneath about 30 mm of packing concrete. Then the bottom layer of bricks. Outside the dome I'm just going to keep packing it on till I figure there is enough.

So I understand the batting doesn't work in compression. Well, I know vermiculite is used to insulate steel chimney liners so maybe a local chimney sweep/installer would be a contact.

The key is not to compress your insulation actually. Obviously underneath take a fair bit but the outside shell will only be on basically under its own weight. Imagine a brick dome in a brick box that's then filled with verm and capped.

A brick dome has to be a feat in itself. I guess that's like intersecting arches with a shared capstone. Or...
"Guastavino Vaults were desired because they were marketed to be completely fire resistant, highly efficient structurally, and incredibly fast to build." Link

I'm actually going to build a tunnel. ...dome was misleading.
More structurally sound, easier also more conducive to the bricks I'm using.
I'm going to use flexible pallet spacers as forms. I will build the first few courses then bend the things in place...choc them up and go for it.

One of my friends is a mason and built this killer fireplace stacking rocks. It was a double arch affair you would like it. What was amazing is that you could feel the heat from it in the kitchen which was off a ways and at an angle. I wonder what heating effects away from your unit you will get you should take a thermometer and move it around. I know you are planning on some kind of temperature control of the oven but I'm thinking about along the sides of your arch for example.
Anyway you are definitely into this project I give you kudos.

Ok so I decided to do the o en before the work area slab for access reasons and so I don't trash it.
Here is the first course with its inch half verm then inch half concrete layer. First verm for insulation then concrete for that little bit more mass.
Let that set for a few days then did this today
[url=https://files.shroomery.org/files/17-31/192019246-20170805_170756.jpg][/url
Can't be bothered fixing that
So basically did the vertical courses of the oven itself next is the dome. I also have started the outside structure and back filled with verm sand and cement. I just wanted to make sure the inner walls don't try and spread when I do the roof.
After the roof is the door arch. Then the chimney box arches. Then the chimney.

On second thought it kind of looks like a cremation chamber so don't worry.

Straight of the sea usually. Salts already showing on the bricks after that recent storm.
Its safe as houses....I just sat on it. I may convert under the concrete work area into a dog kennel... Could probably squeeze you in there.

Cheers. Little by little. Weathers going to shit again this week plus life stuff so it may be the last installed t for a while. I may be able to whack the back and front up in an arvo though so we shall see.
