Sheffield Pottery : America's Premier Clay Maker
Clay manufacturing at Sheffield Pottery is completely unique in the industry. We have expanded our production line to include additional
machinery setting a new standard for the clay industry . Dry clay ingredients are are precisely weighed in our custom batching system, wet mixed in our world class Eirich mixer, and much or your clay is additionally processed in our Sweco 72" flow through separator and an iron filtration magnet which is used by no other clay maker in America .
THE SWECO UNIT enables us to dry screen the entire
batch of clay as it goes through the production process.
Problematic materials like fire clay, grog and lizella can
be carefully controlled. We have found that normally
clean materials like ball clay, flint and
feldspar can also have oversized
nodules of lignite, wood,
paper, stones and
the entire batch will
ensure that no
contaminants remain. Previously
we only screened the fire clay and lizella components of
our stoneware bodies. By offering 30, 40, 50, 80 and
100 mesh screens we are finding that many of our
earthenware and porcelain customers are benefiting
from the process as well. Many of our stock bodies are
available screened. Any custom or other stock body can
be ordered screened.
THE IRON FILTRATION MAGNET is a four-tier unit
made with "rare earth" magnets. As the dry batches
cascade through the filter it will trap ferrous metal
contaminants that come from processing machinery or
the raw clays themselves. This option can be used with
or without any mesh screen, and will help eliminate iron
spots in the clay.The
powered dry clay is precisely portioned through our custom Batching
System. This system is accurate to 0.5 grams per ton of dry materials
ensuring the consistency of our clay bodies whether we are making one
of our stock clays or your own custom formula.
No other clay makers have the superior Eirich Mixer for the wet mixing of your clay. Some makers do not even wet mix their clays at all. Before going to the wet mix, many of our clays are sent though the Sweco Magnetic Screening unit. This is another process used by no other clay maker in the industry. Your clay is then sent through one our massive, industrial quality, deairing pugmills creating a perfect clay every time !
