I am in south central MO also interested in building with cob. Have been wondering if a cob wofati is possible? From what I have read you just have to be sure and keep the water off of it so if you use a buried pond liner like a wofati to take the rain off and away from the structure I am thinking this is viable. I would not mind mixing materials like sort of wofati timber style on the buried exteriors and cob on the interior with a mixed timber/cob/stone exposed exterior front. Anyone currently building give me a shout I'd like to lend a hand for a weekend and see how things are being done.
As far as coming up with clay in the Ozarks I think this red stuff you find a little deeper has got to be rich in it. I am conducting the water jar test to see about that. When I mixed this red dirt with the water it turned a really great earthy orange color. still waiting for it to settle. I believe the difficulty in our area is going to be sifting out the rocks.

I had a water bottle in my car so I used that and it looks like its all clay but I don't think that can be right. I think the clay stuck to the plastic and messed up the test. Otherwise I just made cob in a water bottle. lol idk I'll get back to you.

If it is the right ratio for cob will it stay mixed rather than settle into 2 layers? I haven't been out for another sample yet but the one on my desk just keeps getting a thicker layer of clear water on top and the rest just looks like orange clay.
still need some help building?
