Copper red glaze and production method thereof, and method for preparing ceramic product therefrom

Abstract

The invention discloses copper red glaze and a production method thereof, and a method for preparing a ceramic product therefrom. The copper red glaze is prepared from parent glaze, a coloring agent and a stabilizing agent, wherein the parent glaze is prepared from the following components in parts by weight: 26 to 32 parts of quartz, 24 to 30 parts of feldspar, 10 to 14 parts of limestone, 12 to16 parts of barium carbonate, 4 to 8 parts of clay, 0 to 4 parts of zinc oxide and 0 to 4 parts of sodium borate; the coloring agent is one or a mixture of a plurality of copper oxide, cuprous oxide and copper carbonate, and the adding amount of the coloring agent is 1 to 4 parts by weight; the stabilizing agent is one or a mixture of a plurality of stannic oxide, ferric oxide, lead oxide and silicon carbide, and the adding amount of the stabilizing agent is 3 to 6 parts by weight. According to the invention, the copper red glaze is bright crimson red, the ceramic product produced from the copper red glaze has high yield and low cost, and can be used for producing domestic ceramic and display art ceramic products.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a copper red glaze, a production method thereof and a method for making ceramic products from the same. Background technique [0002] Copper red glaze is a red glaze fired with copper-containing substances as a colorant by reducing flames. According to archaeological data, the Tang Dynasty in my country has begun to use copper to burn red. In the Song Dynasty, Jun Kiln in Yuxian County, Henan Province had already fired a large number of copper-red spot Jun glaze porcelains; Xuande's bright red (also known as "Ji Hong", "Ji Hong") is the most famous. Copper red glaze was once lost in the mid-Ming Dynasty, and it was restored in the Kangxi Dynasty of Qing Dynasty, and it was fired into Langyaohong, cowpea red and other precious varieties. Since ancient times, this kind of bright red firing has been extremely rare and has been treasured by the world. The coloring of copper in glaze is not ...

Problems solved by technology

As long as there is a slight deviation, such as incomplete reduction or partial oxidation, it may cause graying, greening, and blackening; if the reduction is excessive, smoking and pinhole defects may occur; If the temperature is too high, there may be phenomena such as burning loss

Therefore, the product yield is low
