摘要： THIS APPLICATION DISCLOSES A METHOD AND COMPOSITION FOR PREFERENTIALLY GLAZING PREDETERMINED AREAS OF UNFIRED (GREEN) OR FIRED CERAMIC ARTICLES. THOSE AREAS OF THE CERAMIC ARTICLE THAT ARE TO REMAIN UNGLAZED ARE COATED WITH A FILM OF SUBSTANTIALLY COMBUSTIBLE, DISCRETE (NON-COALESCING), HYDROPHOBIC PARTICLES PRIOR TO THE APPLICATION OF AN AQUEOUS GLAZING SLIP. THE AQUEOUS GLAZING SLIP IS THEN APPLIED TO THE ARTICLE BY DIP, SPRAY, BRUSHING, FLOW-COAT, OR WATERFALL METHODS AND THE SLIP ADHERES ONLY TO THOSE AREAS WHICH ARE NOT HYDROPHOBICALLY COATED. THE RESULTING BODY IS THEN FIRED TO FUSE OR MATURE THE GLAZE AND BURN AWAY THE HYDROPHOBIC COATING. THE INVENTION MAKES POSSIBLE THE USE OF THE WATERFALL METHOD OF APPLYING AQUEOUS GLAZING SLIP TO UNFIRED SHAPED (E.G., PRESSED, EXTRUDED, ETC.) CERAMIC BODIES WHICH ARE TO BE PREFERENTIALLY GLAZED ON THE PLANAR SURFACE AND NOT THE EDGES THEREOF.

摘要： Heat-resistant masking compositions suitable for use in masking vitreous and semicrystalline ceramic surfaces from coating by liquid-sprayed coating compositions to provide permeation-resistant masks which are readily removable even after high temperature firing are described. The masking compositions comprise bentonite clay and a finely-divided refractory inorganic oxide release agent.
