This invention comprises china or ceramic sanitary ware such as toilets, lavatories, bidets, and urinals, and similar articles which are made from materials having at least two contrasting colors and may be provided with an appearance resembling natural stone or marble. The invention also includes the process and apparatus for making such articles. Two or more ceramic ware-forming slips of different colors are combined into a unitary stream but not completely blended when poured into the cavity of a moisture-absorbing mold. Special pouring and filling techniques are employed to facilitate the approximate repetition of a design in the formed article for those who desire to be able to repeat a particular design. Where desired, pouring and blending may also be controlled so as to avoid initial contact between the unitary slip stream and the visible or marketing surface of the mold forming the finished product where a product of a particular appearance is desired. This results in a natural stone or marblelike appearance of the finished product, and the particular design can be generally repeated in subsequent articles. Pouring may also be controlled so as to contact the marketing surface where such marbilized appearance is desired. For those who desire variation from product to product, this can be accomplished by varying color and slip compositions and by mold manipulation. |
