Problems solved by technology

[0003] The production of ceramic products is based on the composition of glaze and its firing process. During the development of thousands of years, many famous glaze compositions and firing processes have been produced in the field of ceramics. The changes are very complicated. Changes in glaze composition, sometimes only subtle changes, and different firing conditions including temperature, air flow, redox environment and even temperature c...

Embodiment 1

[0028] Glaze preparation:

[0029] Get 22 parts by weight of albite, 5 parts by weight of calcium carbonate, 3 parts by weight of titanium dioxide, 20 parts by weight of kaolin, 5 parts by weight of quartz, 8 parts by weight of iron oxide, 20 parts by weight of manganese dioxide and 17 parts by weight of boron block; add water 110 parts by weight, ground into a glaze slurry in a ball mill, and the glaze slurry is passed through a 250-mesh or finer sieve for use; the steps of grinding into a glaze slurry include weighing raw materials, putting into a ball mill jar, adding water, sealing the lid, grinding, and opening the jar lid , release the glaze water, filter, adjust the concentration;

[0030] Product preparation:

[0031] Follow the steps below;

[0032] Blank making, bisque firing at 800°C for 4 to 5 hours, then naturally cool for later use;

[0033] Glazing, the glaze is made by biscuit firing into the porcelain body according to the conventional method, and the glaze...

Embodiment 2

[0040] The process is the same as in Example 1, except that the composition of the glaze slurry is different. The glaze composition of this example is: get 12 parts by weight of albite feldspar, 3 parts by weight of calcium carbonate, 2 parts by weight of titanium dioxide, 15 parts by weight of kaolin, 3 parts by weight of quartz, 7 parts by weight of iron oxide, 15 parts by weight of manganese dioxide and boron Melt 43 parts by weight; add 110 parts by weight of water, grind in a ball mill to form a glaze slurry for later use.

Embodiment 3

[0042] The process is the same as in Example 1, except that the composition of the glaze slurry is different. The glaze composition of this example is: get 26 parts by weight of albite, 8 parts by weight of calcium carbonate, 5 parts by weight of titanium dioxide, 20 parts by weight of kaolin, 6 parts by weight of quartz, 10 parts by weight of iron oxide, 22 parts by weight of manganese dioxide and boron 3 parts by weight of melt block; add 110 parts by weight of water, and grind into a glaze slurry in a ball mill for later use.

Abstract

The invention discloses a rust glaze and a method for making products thereof. The rust glaze is composed of components including by weight: 12-26% of sodium feldspar, 3-8% of calcium carbonate, 2-5% of titanium dioxide, 15-20% of kaolin, 3-6% of quartz, 7-10% iron oxide, 15-22% of manganese dioxide, and the balance boron clinker. The method for making the products includes glaze slurry preparation and product preparation, wherein blank making, furnace sintering, and cooling in the roduct preparation use strict temperature control conditions and a uniform glazing method. Ceramic products made by the rust glaze composition recipe of the present invention and the sintering process have unique qualities and characteristics, have an iron rust-like appearance, are loose as removable rust, present brownish red, and present a layer of rust crystal light on the glaze surface. The sintering process is easy to control, the temperature control of sintering achieves energy efficiency and reliability, and the rate of sintered qualified products is high.

Description

technical field [0001] The invention belongs to the fields of daily-use ceramics and technical ceramics, and in particular relates to a rust glaze in high-temperature kiln-changing color glaze and a production method of the product thereof. Background technique [0002] Ceramics has a long history in China. In the course of thousands of years of development, countless excellent ceramic works and crafts have emerged. Most of the products and crafts are still passed down by the world and contribute to the well-being of mankind. Henan Jun porcelain kiln variable glaze flow glaze, Henan Ru porcelain crack glaze, Zhejiang Longquan celadon glaze, Ge kiln gold wire and iron wire crack glaze, Guangdong Foshan low temperature glaze, Fujian Jian kiln Tianmu glaze, Taiwan firewood kiln variable glaze, etc. Typical. [0003] The production of ceramic products is based on the composition of glaze and its firing process. During the development of thousands of years, many famous glaze com...
