Under this definition cob would be considered "light-clay" (straw being
the fiber).  I could be mistaken, but in my experience "light-clay" refers
to a specific technique also known as lietchlem (spelling?) in which straw
is given a very thin coating of clay slip, allowed to dry until tacky, and
then rammed into a form.
