Cob: Mold in Home

YQ,
    it's certainly worth a try. Deciding on a percentage would be an 
interesting study.   Sorry to hear about the mushrooms though, I guess 
they weren't the eating kind.....    From my limited knowledge of making 
naturally fermented pickles, bacon, ham, and  sauerkraut, etc.,  I 
usually use a 2.5% salt by weight, to keep out bad micro-organisms. 
 Lacto Bacillus, the good guys can still live there and produce lactic 
acid, that good sour taste.   I would for some reason, recommend using a 
more natural salt for testing and not the ultra processed table salt 
stuff American's think of as salt, like mortens, etc.       People near 
the ocean, could scoop out water, evaporate half the water off  and have 
about a 6% salt content solution then (evaporate all the water and you 
have corns of salt left and can make corned beef)..    

Unfortunately I don't know what effect salts would have on clays 
chemical/mechanical bonds.   Good idea and worth looking into, in my 
opinion.

Note, however that I don't think that mold is a problem for cob 
buildings built sensibly.   In some cases like a humid bath room it 
might be useful.
