Abstract

The invention discloses a fancy glaze for decorating medium-temperature daily ceramic, and a use method thereof. The base formula of the fancy glaze comprises 10-14 wt% of kaolin, 20-40 wt% of quartz, 2-6 wt% of albite, 2-6% of feldspar, 7-14 wt% of calcite, 7-12 wt% of wollastonite, 2-6 wt% of zinc oxide, 2-6 wt% of titanium dioxide, 2-6 wt% of bone ash, 2-6 wt% of calcium phosphate, 3-6 wt% of ammonium molybdate, 1-3 wt% of cerium oxide, 1-3 wt% of yttrium oxide, and 2-5 wt% of an external coloring oxide. The use method comprises the following steps: carrying out mixing, ball milling and sieving on the above raw materials, applying the obtained raw materials to a medium-temperature daily ceramic briquette, and carrying out medium-temperature one-time sintering to obtain the product. Medium-temperature daily ceramic decorated with the fancy glaze has the advantages of simple process, high adaptability and unique effect, so the fancy glaze has broad market prospect.

Description

technical field [0001] The invention belongs to the field of ceramic glazes, and in particular relates to a decorative glaze for medium-temperature daily-use ceramics and a use method thereof. Background technique [0002] With the improvement of living standards, people are increasingly pursuing high quality of life. Objects used in daily life are no longer simply satisfied with the value of their use, but also require ornamental value. At present, in terms of exterior decoration of daily-use ceramics, there are already a series of decorations such as on-glaze decals, reliefs, over-glaze colors, under-glaze colors, color glazes and comprehensive decorations. In order to meet people's high-quality life needs, decorative glazes, as artistic porcelain decorations, are applied to daily-use ceramics - floral glazed daily-use ceramics emerged as the times require, and are more and more popular with people, and the market prospect is very good. [0003] The so-called flower glaz...
