Check out this famous builder's method which looks pretty sloppy but he uses a sand form in this set of photos. I like that refractory liquid mortar he pours over the entire dome. Seems like his whole build procedure saves a lot of time.

You can basically build a dome with a simple entry and no vent. Fresh air enters through the lower area of the entry while the hot gases exhausts out through the upper portion of the entry. You can singe your eyebrows if get too close to the entry though...
I just opened this link (I knew I had skipped over a couple of them and thought I'd go back and check 'em out. I also had a chance to read Thermal Mass'es Thread. All good stuff... Thank for posting!
