Karangi Dude's Mobile Oven

[BrixxGrill]

I mixed the vermiculite with portland cement and filled the cavity around the base of the oven to the height of the hearth leaving enough room for a granite landing
At this stage I used some heat beads to create a little heat to help cure the high temp mortar

Absolutely fantistic pics and explanations. Thanks so much for sharing! A couple of questions for you: Do you find that you have sufficient stored heat/thermal mass with only the cooking floor to avoid having the floor start to get cold? Do you feel it would have been useful to have a little more thermal mass right under the cooking floor? Maybe I missed it, but how much fibre insulation did you use around the walls and dome? Thanks again!
