Rust glaze and method for making product thereof

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...

AI Technical Summary

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 change process will make the final result completely different, so ceramic production is very fine, It is a technical process with rich changes and challenges, and because of this, the field of ceramics has never stopped exploring and innovating.

[0004] At present, there is no glaze composition, firing process and products that are brownish red, as loose as rust spots that can be removed, and a layer of rust crystal light appears on the glaze surface.
