Problems solved by technology

[0002] The application of metallic luster glaze on ceramic products has been for a long time. As far as the sintering method is concerned, so far, the common metal glaze used in both architectural ceramic tiles and daily ceramic products is generally iron phosphate. Or the two major formula systems of lead-based glaze composite manganese-copper-titanium-nickel; due to the raw material formula and firing process, the application of ordinary metal glazes is not satisfactory in many aspects: or the glaze color is less, Monotonous, and lack of natural changes in glaze color and luster, which makes the decorative embellishment effect of the product greatly reduced; or lead and cadmium exceed the standard, which limits the wide application of glaze in the field of daily-use ceramics

Abstract

The invention discloses Grignard metal glaze with silvery white color effect, which is prepared from washing mud, rock quartz, lithium carbonate, albite, iron phosphate, aluminum phosphate, zinc oxide, a color developing agent, rutile and manganese carbonate. The mass percentage of each component is respectively as follows: 1-6% of washing mud, 1-6% of rock quartz, 5-15% of lithium carbonate, 30-45% of albite, 15-25% of iron phosphate, 5-15% of aluminum phosphate, 0.5-3% of zinc oxide, 3-10% of a color developing agent, 3-8% of rutile and 0.5-3% of manganese carbonate; the processing technology comprises the following steps: 1, selecting and preparing materials; 2, performing material treatment; 3, firing; and 4, utilizing residual glaze slip. The metal glaze has rich colors and strong metal texture; and the technological process is basically the same as that of common ceramics, the technological parameters and the firing control range are wide, especially the firing curve of the product is the same as that of the common ceramics, special devitrification and heat preservation are not needed, and an enterprise can rapidly enter a stable production state.
