Cob Re: Is Linseed Oil All You Really Need?

[John Straube]

Thank you Mr Davis for the nice report of your experimental information. 

I would like add a few caveats for the interpretation of the results.  
All samples of lime/cement etc should be fully cured first, becuase the 
moisture content and thus mass can change becuase of chemical reactions, 
not just because of moisture absorption.

Linseed oil should not be applied to fresh lime-cement plasters becuase 
their initial alkalinity is to high.  The linseed should be added after 
about one year if possible.  The application to dry clay is probably OK, 
and your results are very encouraging.

I would not apologize for your lack of equipment -- I think you have 
provided a  lot of info without it.  Thamks again.
