Claim 1
Independent Claim
181 words
A METHOD OF PRODUCING NOVEL CERAMIC ARTICLES WITH AN IMPERVIOUS TENACIOUSLY ADHERING GLAXED SURFACE IN WHICH DIFFERENT COLORED TONES PRODUCE A MARBLEIZED AND TEXTURED DECORATIVE EFFECT, COMPRISING: APPLYING A FIRST BASE GLAZE COMPOSITION TO THE SMOOTH SURFACE OF A FINELY POROUS CERAMIC COMPOSITION ARTICLE TO FORM A CONTINUOUS COATING THEREON OF VIRTUALLY UNIFORM THICKNESS, SAID BASE GLAZE COMPOSITION CONTAINING IN MOLECULAR RATIO LESS THAN 0.7 NA2O, K2O AND PBO COMBINED TO 1.0 SIO2 AND ADAPTED TO NOT REACT WITH, FLUX AND DESTROY THE CERAMIC COMPOSITION; APPLYING A SECOND GAZE COMPOSITION COATING TO THE ENTIRE SURFACE OF SAID BASE GLAZE COATING TO FORM AN OVERLYING LAYER NOT SUBSTANTIALLY THICKER THAN THE SAID BASE COATING, SAID SECOND GLAZE COMPOSITION HAVING A MATURING TEMPERATURE RANGE NOT LESS THAN ABOUT TWO CONES ABOVE THE MATURING TEMPERATURE RANGE OF THE BASE GLAZE COMPOSITION; AND FIRING THE ARTICLE SO COATING TO A TEMPERATURE WITHIN THE MATURING TEMPERATURE RANGE OF SAID BASE GLAZE COMPOSITION WHEREBY THE OVERLYING SECOND GLAZE COMPOSITION COATING DIFFUSES INTO SAID BASE COATING AND BECOMES DISCONTINUOUS DURING FIRING AND PRODUCES AN OVERALL MARBLEIZED TEXTURED EFFECT.
