Manufacturing method of underglaze white double crystal fancy glaze

Abstract

The invention relates to a manufacturing method of an underglaze white double crystal fancy glaze. The method comprises the steps of preparing materials according to a formula, manufacturing a frit, sieving by using a ball mill and modulating, wherein the frit is made from borax, potash feldspar and quartz; a ground glaze is made from potash feldspar, zinc oxide, calcite, quartz and frit; and an overglaze is made from frit, barium carbonate, iron red, potash feldspar, titanium oxide, zinc oxide, bentonite, quartz, iron oxide red and zirconium silicate; dry grinding frit materials, burning the frit materials at 1250 DEG C, and cooling fast to obtain the frit; sieving ground glaze and overglaze materials by using the ball mill; wet ball milling, and sieving by using a 250 mesh sieve; modulating the ground glaze and the overglaze: mixing the crushed frit respectively with the ground glaze and overglaze materials which are sieved and wet ball milling mixtures so as to modulate the mixtures into slurries at 45-50 baume degree; burning: spraying glaze on a green body, wherein the thickness of the ground glaze is 0.4-0.7mm, the thickness of the overglaze is 0.3 mm, and feeding the green body into a roller way to be burnt into the underglaze white double crystal fancy glaze in an oxidizing atmosphere; after burning, natural, smooth and crystal clear decorative patterns can be generated.

Description

technical field [0001] The invention relates to a preparation method of a double-layer crystal flower glaze with white flowers in the glaze. Background technique [0002] White flower double-layer flower glaze is a kind of crystal flower that reacts through the combination of bottom glaze and surface glaze. The glaze layer is controlled by oxidizing flame to form various patterns of pattern glaze, which has special artistic effect and modern sense. It is favored by domestic and foreign markets, but there are some shortcomings in the existing technology: 1. The color is unstable and the color difference is relatively large. 2. The glaze has high fluidity at high temperature and is easy to stick to the bottom. glow. Invention content: [0003] The purpose of the present invention is to aim at the shortcomings of the existing double-layer crystal flower glaze, and develop a new manufacturing method of double-layer crystal flower glaze with white flowers in the glaze. The met...
