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 with the copper red glaze. Background technique [0002] Copper red glaze is a red glaze fired by reducing flame with copper-containing material as colorant. According to archaeological data, my country has begun to use copper to produce red in the Tang Dynasty. In the Song Dynasty, Jun kilns in Yu County, Henan Province have made a large number of copper red-spotted Jun-glazed porcelain; in the late Yuan and early Ming Dynasty, the one-color red-glazed wares were fired in Jingdezhen. Xuande's bright red (also known as "Jihong" and "Jihong") is the most famous.
