Tim--Carl Steen mentioned several references on brickmaking. Here are the
details:
 
My own dissertation is Wayne, Lucy B., 1992, Burning Brick:  A Study of a
Lowcountry Industry, Ph.D. dissertation, University of Florida College of
Architecture.  This covers plantation brickmaking in the vicinity of
Charleston, SC--essentially all hand-made bricks.
 
The Wheaton reference is:  Wheaton, Thomas R., Jr., Mary Beth Reed adn Mary
Elizabeth Gantt, 1987, The Jimmie Green Lime Kiln Site, Berkeley County,
South Carolina.  Garrow & Associates, Atlanta, GA.  Same area and time
period as my work.
 
Yes, Brockington and Assoc. have excavated several brickyard sites in the
Charleston area.  Again same area and time period as my work.  But as far as
I known, the only thing available at this time addresses an associated slave
occupation--no brickyard publications yet.
 
I don't know about Cotter's work at Jamestown, but Harrington did excavate
an early kiln.  Reference is:  Harrington, J. C., 1950, Seventeenth Century
Brickmaking and Tilemaking at Jamestown, Virginia, The Virginia Magazine of
History and Biography 58(1):16-39.
 
For Colonial Williamsburg, in addition to Carl Steen's own study (which is
in manuscript from Carl or C.W.), see Weldon, Bill, 1990, The Arts and
Mysteries of the Colonial Brickmaker, Colonial Williamsburg, The Journal of
the Colonial Williamsburg Foundation 12(4):7-15 and his 1990, The
Brickmaker's Year, The Colonial Williamsburg Historic Trades Annual 2:1-40.
 
South also did a kiln at Brunswick--see South, Stanley, 1963, Exploratory
Excavation of a Brick Kiln at Town Creek, Brunswick County, NC.  Ms. on file
NC Dept. of Archives and History.
 
Most of these studies are simple clamp kilns with hand molding.  The Gurcke
reference which several people passed on is excellent, as is the Nance's
Ferry study.  The Waverly study may have some oral history relevant to
brickmaking--Adams is good at that.  Look in the architecture literature for
lots of information on the technology of brickmaking and its development.
Another area for information is that of ceramic engineering or technology.
