Mass is not insulation.

Polo,

If I remember correctly from our previous encounters your oven has insulation between the structural hearth and the cooking floor correct?  That is a major change from the original design of that oven and eliminates the major issue most people have with it.  It is still a very massive oven best suited for commercial bread baking, but it is well insulated when built that way.

It is built to the "Ovencrafters" plans. Either 3.5" or 4" of vermicrete (can't remember at the moment), 3.5" structural hearth, and 3.5" firebrick (working) hearth (from the bottom up). No design change, no deviation, straight Alan Scott style. I wasn't too thrilled with the  consistency of my vermicrete mixture, but it worked OK.

Is there any difference using the perlite vs vermiculite?

Not really, either works fine, they are different forms of the same mineral.

After I put up the soldier course and construct the dome, I have about 4 inches on each side to pack in I will do a 12 - 1 if that sounds right. Now regarding the buttress after putting the insulation I'm going to have about 4 inches of room on each side for insulation because I left the old brick that was there would the brick be enough of a buttress or does a layer Of cement need to over the insulation?

does anyone have any thoughts on using insulating firebrick to make a buttress around the soldier course with a gap of a few inches for some rebar and refractory cement ?
