Little Cob Oven
Here is a little cutie oven that was a test to see how it would hold up (covered with a tarp when not in use) in the Maine, US climate.

I had to actually buy some clay powder for this project, as (after soil tests and another tinier oven test just did not have enough clay to hold it together) the soil here is very sandy and rocky, but not too rich in clay. For the first layer, I used some (a small amount) of the soil here, plus sand and clay and a little water and danced and danced in that cob mixture. Then, I used clay and pine sawdust/shavings for the insulating layer and a clay slip coating on the top layer. So far, especially the first layer, is holding nicely. If it makes it through the winter season, I will do a larger version in a similar way.
Sealants this is new!
Saw on a reel they use soap then rub on the Canuba oil. It comes in a round can. They used this to seal for a shower. Wondering how well this works.

Are you talking about Tadelakt? That usually goes over cob to waterproof it, is lime-based and also does use olive oil based soap and burnishing with tumbled and smooth semi-precious stones. It works very well, but is a little bit different technique from cob. It creates a crackled finish and looks lovely when finished. It is very water resistant, too.

You can also buff it with wax after it cures for further protection from water.
I framed a door
We got this cool door on Facebook marketplace. It has a rounded top, so I had to build an arch for the frame. Started off by making a rectangle, right where the arch starts, then once that part of the frame was in place, I could cut the top of the rectangle and put in the arch, if that makes sense. Chiseled some slots for the hinges. I still need to make a round window for the door, probably I will cut some acrylic or plexiglass.

Very cool! Looks like you are doing a terrific job with this project!
Hi all! 👋 New here and happy to find this group
I'm a builder based in southern Utah — would love to connect with any other Southwest folks in here! I recently got to work with Sir Cobalot, which was a great experience, and I'm looking forward to going deeper — his cob oven course is next on my list. Has anyone here done an oven yet? I'd love to hear how it went! Feel free to say hi as well 👋 I attached a photo of a recent sculpture I did out of cob that I'm very proud of!

Looks fantastic! Well done! I have built several ovens and prefer to do the easy peasy sand sculpture method with them. I personally find this to be the quickest and easiest way to do an oven build. I think that ovens are mostly very forgiving and can be sculpted and finished in similar ways to cobbins. You are clearly super creative and talented and will probably make many more beautiful cob structures and sculptures! Wishing you all the best!

@Valerie Østvik You are most welcome. Thank you for sharing your beautiful project with us!
Cobbing and earthen plastering demo
Hey, I just thought I’d share with you a little clip showing how I’m using a cob mix as a finish plaster on exterior. When this coat is dry in a couple weeks, I will apply a clay paint with equal parts sifted Clay, very fine Sand and either flower paste or a plant-based cellulose as the binder. When this is all dry, I can either apply a linseed oil,, a fermented, nopal cactus juice or something called water glass, which is also known as sodium silicate. I’ve actually never used this before. It comes in a gallon liquid form.I’m curious to try it out. I’ll let you know how it does I’ve heard it works well. It’s true. I usually do a lime plaster for the exterior, but I actually much prefer doing Earthen plasters .
