Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
97 words
IN A GLAZING COMPOSITION FOR CERAMIC SUBSTRATES, SAID GLAZING COMPOSITION CONSISTING ESSENTIALLY OF A AQUEOUS DISPERSION WHEREIN THE SOLID PHASE CONTAINS SILICA, KAOLIN AND AT LEAST ONE MEMBER OF THE GROUP CONSISTING OF WATER-INSOLUBLE SILICATES, ALUMINOSILICATES AND OXIDES OF BORON, POTASSIUM, SODIUM, CALCIUM, ALUMINUM, BARIUM, STRONITIUM, MAGNESIUM, LEAD, ZINC AND ZIRCONIUM AND HEAT-REACTIVE PRECUSORS OF SAID SILICATES, ALUMINOSILICATES AND OXIDES, THE IMPROVEMENT OF ADDING BETWEEN 0.01 AND 10%, BASED ON THE WEIGHT OF SAID GLAZING COMPOSITION, OF A WATER-SOLUBLE MATERIAL SELECTED FROM THE GROUP CONSISTING OF IONIC AND NON-IONIC SURFACTANTS IN ORDER TO IMPROVE RESISTANCE TO CRAWLING.
