I will get together a handfull of referneces with full citations on
the clay used in tobacco pipe manufacturing in England and send it
out to the list after I recover from my annual over indulgences at
the SHA.  Meanwhile, the three best researchers on
clay tobacco pipes from colonial sites were Ian Walker, John
McCashion and Duke (L.T.) Alexander.  Unfortunately they are dead.
Duke's complete archive of materials is currently being housed at the
Archaeology Laboratory of the University of Delaware.  Ian's material
may still be at Parks Canada in Ottawa but I am not sure about that.
The New York State Historical Society should still have all of John's
stuff.  The best single researcher on Dutch clay pipes is Don Duco
but much of his material is in Dutch.  Also check your card catalogs
for anything by Adrian Oswald, Byron Sudbury, and James Murphy -
particularly Adrian Oswald for colonial era sites.  Issues of
HISTORICAL CLAY TOBACCO PIPES  are still avialable and I know a book
seller who specializes in Tobacciana if you are interested.
