Moist Pottery Clay
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 pottery 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 other unwanted material. Screening 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 !
