Had six firings so far, gradually built up temp to this point, 250celsius yesterday & 350celsius today. Still using heat beads added to kindling mix and spreading around interior to different spots, chimney is drawing well, even had some flamage out the ceiling & up the chimney tonight which is spectacular, amazing how much heat you get from such a small quantity of fuel, dome is still cold to the touch

Looking forward to having a couple of cook offs over Easter at full temp prior to adding the final layer.

With the final render layer, is it better to do a few thin coats as opposed to one or two thicker coats, the vermiculite has a few spots where I need to add more material to give a uniform shape particularly after drying the stuff out

You will find that the more you use your oven, the better it seems to get. Faster heat up, less fuel used, better heat retention. I think it's due to the elimination of moisture, a fair amount of energy is required to turn the water to steam and of course any moisture in the insulation area reduces the insulation value. You're in for a treat, keep firing.

I used a product made by Dryvit.

That's exactly what I want to use to finish my base. We watched contractors apply Dryvit to the exterior walls of a house down the street from us last year and I figure if it's suitable for exterior house walls around here, it'll hold up well on the base of my oven - trouble is, it seems only contractors can get their hands on it around here.

Were you able to buy it at a Lowes/Home Depot/ or similar type of store?
It may be time for me to take a run to Syracuse again ...

You can purchase DryVit at a plaster building supplier. I bought mine here.
