Series of multi-layered zebra color changing glaze and product preparation method

Abstract

The invention discloses a series of multi-layered dappled color changing glaze. The color changing glaze is composed of bottom glaze, middle glaze and surface glaze. The bottom glaze comprises: 15-20parts of medium temperature 1# lead-free frit, 15-20 parts of nepheline syenite, 35-40 parts of medium temperature 2# lead-free frit, 5-10 parts of quartz, 5 parts of calcium carbonate, 3 parts of barium carbonate, 10 parts of kaolin, and 3-6 parts of a coloring oxide or lead-free ceramic coloring material. The middle glaze comprises 40-45 parts of nepheline syenite, 15-20 parts of medium temperature 1# lead-free frit, 10 parts of calcined talcum powder, 8-10 parts of quartz, 15 parts of calcium carbonate, 7 parts of calcined zinc oxide, 5 parts of kaolin and 3-12 parts of a coloring oxide orlead-free ceramic coloring material. The surface glaze comprises 20-25 parts of nepheline syenite, 10-15 parts of boron silicate, 10-15 parts of low temperature lead-free frit, 8-10 parts of quartz, 15 parts of calcium carbonate, 3 parts of barium carbonate, 7 parts of calcined zinc oxide, 7 parts of glass powder, 10 parts of kaolin and 3-5 parts of vanadium pentoxide. A preparation method comprises preparation of three layers of glaze, glazing and firing. The product patterns have three-dimensional aesthetic feeling.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and specifically refers to a series of multi-layer mottled color-changing glazes and a preparation method thereof. Background technique [0002] In the mid-Northern Song Dynasty, with the publication of "Tea Records" by the famous calligrapher Cai Xiang, the tea fighting culture spread in the court and the public, and Jian Kiln entered a period of prosperous development, and the production scale continued to expand. Partridge spot, obsidian change. As the main product of Jian Kiln, the Rabbit Haozhan is characterized by crystallization patterns distributed on the surface of black glaze like rain silk stripes. [0003] The main reason why Jianzhan is favored by tea connoisseurs is its glazed markings. The essence of markings includes the material and formation process of markings. After a series of physical and chemical changes in the high temperature stage, the iron oxide in the glaze crystal...

Problems solved by technology

[0010] The present invention provides a series of multi-layer patterned color-changing glazes and a preparation method thereof to solve the problem that the body of existing glazed patterned products is easily deformed or cracked in the drying stage, easy to bubble in the high-temperature reduction stage, and the patterned glaze layer is thick and flowing. High resistance, high firing temperature and narrow range, unstable crystalline substances affect the shape and color of the markings, etc.
