agreed. I thought higher temps were better..I didnt realize that they were measuring exterior temps and thus heat loss.

The good news is that I can easily make up it up 2:1 vermiculite vs blanket as my enclosure will have plenty of room and ill have plenty of vermic with a 60cuft minimum buy....

When you say you can get a "ton" straight from the mine, I take it that you mean that this is the raw material. This will do you no good. The material silcate material that is mined has to be processed before it becomes vermiculite or perlite. The processing is to heat it up to a high temp so that the moisture inside expands or pops the silcate, then it becomes a material that you can use as insulation.

If your support is a concrete slab, you can place the insulating material directly on that, then the fire brick hearth upon the insulation.

I attached a brick exterior veneer over a render shell over the insulation. You might want a neater finish but I'm pleased with a more rustic finish

The insulation blanket draps over the oven and around the chimmey. You can then help hold it in place with chicken wire. You then can put your mortar over this, the chicken wire will act as reinforcment for the mortar.

Hi Dallas,
Did you receive my private mail? If not, I was under the impression that you were referring to you oven floor, not the dome. Am I right. If you meant your dome, then another layer of fire bricks are not used over the insulation. You can use stucco to maintain the igloo shape or you can build an enclosure for it and add additional insulation.
