  • Patent number: 4521355
    Abstract: A method of producing decorative ceramic ware is disclosed. In the first step, a flocculant is added to an aqueous suspension containing as main solid components a fibrous material and a ceramic raw material clay, followed by preparing ceramic raw material sheets from the suspension by the ordinary paper-making method. Prepared are at least two kinds of ceramic raw material sheets differing from each other in color after firing. Then, the stacking-cutting operation of the sheets is performed at least once, in which the different kinds of sheets are alternately stacked, followed by cutting the stacked mass in a direction not parallel with the surface of the raw material sheet. The cut piece is formed into the desired shape and, then, dried and fired to produce a striped or checkered decorative ceramic ware. This particular method permits industrial production of ceramic ware.

  • Patent number: 4421599
    Abstract: The fibrous material is for the preparation of a sheet material containing large amounts of inorganic fine powders or inorganic short fibers by a usual paper-making method. A raw material for forming the fibrous material is previously impregnated with a polymer flocculant of the polyacrylamide type or the like in the amount of 0.01 to 5% (dry solids). The fibrous material is adaptable for sheets which can be prepared easily by individuals at home as well as at factories. The fibrous material can be utilized for a wide range of application, for example, for various ceramic products, construction materials, papers for special use, filters and so on and for recovery of solids from waste water or the like.
