[Cob] cold damp cob

[William Pittman]

  Salt will dry out the cob faster, but that may come at a cost of the
durability of the cob. Maybe interfering with the sand and clay joining
together.

I found a research paper regarding salt and the way it affects building
materials, and how the negative effects can me mitigated. The bad thing is
it costs $31, but it might prove to be worth the cost for those wanting to
dry cob out faster.

In the desert SW cob can dry in one day. We were amazed this pass summer
that we were able to plaster the next day. I'm building a cob bench right
now in Pasadena and it's taking longer than I want it to. The clay we used
in the desert was filled with salt. Maybe that could work and keep the
sprouts from growing. There was a salt film however when it dried, but oils
took care of that.
