Forming the body
          Next, the body of the porcelain is formed. This can be done

          using one of four methods, depending on the type of ware
          being produced:

                  i.    Stiff plastic forming, which is used to shape less
                        plastic bodies. The body is forced through a steel die
                        to produce a column of uniform girth.




                  ii.  Pressing, which is used to compact and shape dry
                       bodies in a rigid die or flexible mold. There are several

                       types of pressing, based on the direction of pressure.



                  iii.  Slip casting, in which a slurry is poured into a porous
                       mold. The liquid is filtered out through the mold, leaving
                       a layer of solid porcelain body. Water continues to

                       drain out of the cast layer, until the layer becomes
                       rigid and can be removed from the mold.
