Cob: on salt

[Wendy Smyer Yu]

One thing to watch out for, as my sister in law in China will attest, is 
that salt in the mix WILL cause rust in any sort of rustable metal in 
contact with it.  Seems that they're building things with a lot of salty 
beach sand in the mix in china and there's consequent rusting of pipes... a 
real bummer to say the least, when it all leaks and your kitchen wall has to 
be knocked out...

so, not to say that salt couldn't help, but I'd watch out for things like 
this...
