All in the title...
The clay must be mixed with sand, and the % vary according to the earth we use...
Then, how can we estimate our local earth?

Thanks, it looks really good, I will try it!

What would be the natural % that can be used to make cob without needing sand?

I guess we must avoid any organic matter to make cob?
only earth from deep down?

Great info, best description I have found so far and includes basic tests to let you know that the stuff you made is good to use.

That is the permie way, thanks!

It is so much saving energy that we do not spend our time looking for the same things!
