[Cob] rice flour

[Amanda Peck]

Interesting.  I've heard about rice hulls (light-weight, flammable only with 
difficulty, but if you can get it burnt it makes a fine pozzolan for lime) 
and rice straw (hard on the hands and feet, but strong) having building 
uses.  First time I've heard about plain rice.

I was watching a Nat'l Geo on the Great Wall and was
interested to see that part of the wall had mortar
which had outlasted the rock.  The key ingredient was
rice flour.  I did a searcha and found a site which
says that a lightly boiled rice paste is one of the
strongest glues for paper goods.
