Frank,
What people on this list are referring to as "Light Clay" is straw that has
been made gooey by mixing it with clay slip.  It is then rammed into
forms -typically between posts in a post & beam building - and then left to
dry.  It makes a natural and rather insulative wall material.
Thanks anyway,
