ABSTRACT
As noted in the previous chapter, the ideal consistency of cob for placement on
the wall is when the material has attained a fairly stiff but plastic state, some-
what like dough or putty. It should hang together in fairly large clods that can
be easily lifted with a fork. If the cob disaggregates into small pieces it is too
dry and would need to be wetted and re-mixed. As a general guide, a lift of cob
should be equal to the width of the wall, though it is possible to construct
higher lifts, up to one metre, if coarse, sandy soils are being employed.
