Patent ID: 7303721

Claim:
A method for forming a glazed ceramic article comprising the steps of: providing a glaze composition in aqueous liquid suspension, said glaze composition comprising a clay component in aqueous liquid suspension; feeding the glaze composition in suspension, into a forming cavity of a porous mold having an inner surface to create and form a first glaze film of desired thickness that uniformly covers the inner surface of the forming cavity by absorption of liquid phase of the suspension; thereafter feeding a slip into the cavity of the mold to form a wall of the article by absorption of liquid phase of the slip, said article wall having an outer surface and an inner surface, substantially the entire outer surface of the article wall being covered by the first glaze film; feeding the glaze composition in suspension, into the forming cavity of the porous mold in which the first glaze film and the article wall have already been formed, to create a second glaze film that covers the inner surface of the article wall by absorption of liquid phase of the glaze composition suspension; and thereafter firing the article to provide said glazed ceramic article.
