I really don't think cob is the right material for a wood- fired oven. Clay? Yes, of course, there is a long history of that material being used. But the plant matter in cob, after heating and drying will become an insulator, when you want the heat to permeate everything and be retained in the walls of the oven. With cob, I'm guessing you'll get surface penetration at best, and short term heat retention.
Better, I think, would have been to use bricks, or to do your best to refine your forest clay down to eliminate impurities - and then make the oven entirely out of clay. Yes, I have built a backyard pizza oven. I used a dense, clay brick, and I covered that with 2 inches of refractory concrete, which is just ready mix concrete with a good shovelful of powdered fire clay added to the mix.
Cob is interesting as a building material, but I wouldn't use it on an oven.

Once the oven was deemed a potential failure, did you video the correction by adding to the upper structure. One thing I need to say is that I have had many failures from my prospective. These i did indeed learned from. I am impressed by your positive approach, even when it is a disappointment. Hope you are well and prospering from these endeavors. Mike from Oregon.

Man, I wish I had the land and time to do such things. sadly living the City life as a freelance designer rarely gets you out to the forest. Also all the land around here is owned by either the state or already is private property. lol

I made a large pizza spatula out of an old circular saw blade.
Stainless. Thin. Easy to work with. VERY USEFUL tool from repurposed, normally discarded things.
I would love to see if anyone else has done something similar.

Did you use those yellow high temp fire bricks at bottom? If so they need really high temps to get them hot. I have those in my gas forge and those need to really high temps and longish time to get them heated so they keep heat.

I remember when Richard Dreyfus made the mountain of potatoes in Close Encounters of the Third Kind. Sorry, just had to reminisce for a second.
