[Cob] more on lime wash

[Howard Switzer]

The color of lime plaster can be due to the color of the sand used.  I've
had some very bright white walls using clean white sands, but peachy walls
using sand that had some red clay or iron in it, and gray walls with other
sands, sands uncleaned may have color pigments in it.  If just a straight
lime white wash on earthen plaster it may take several coats to get to
white.
