Problems solved by technology

[0003] With the deepening of people's understanding of kiln-changing glaze, the beauty of kiln-changing defects has gradually been loved by people, so it is regarded as artistic enamel and appreciated by people. Especially in recent years, kiln-changing glaze can be used on daily tableware to make artistic ceramics practical Chemical use is the future development trend, and the existing ceramic patterns can no longer meet people's needs
[0004] In the patent document (CN109081589A) of the applicant's earlier application, a feather-shaped kiln-changing glaze is disclosed, which uses Fe 2 o 3 and MnO 2 As a coloring agent, ceramic melanin is used as a coloring correction agent to obtain a feather-shaped kiln-changing glaze with black and white colors, which meets the needs of users who prefer this color, but the variety of kiln-changing glazes with this color is still too single to satisfy other colors. Therefore, it is necessary to continue to develop kiln-changing glazes with more colors

Abstract

The invention discloses copper-series flambed glaze. Ground glaze of the copper-series flambed glaze is prepared from the components: SiO2, Al2O3, B2O3, Na2O, CaO, K2O, CuO, BaO, MgO, and less than one part of other components; and overglaze is prepared from the components: SiO2, CaO, Al2O3, K2O, B2O3, Na2O, ZnO, Ca3(PO4)2, TiO2, and less than one part of other components. The invention further provides a preparation method of the copper-series flambed glaze. The preparation method comprises the steps that (1) glaze slip of the ground glaze and glaze slip of the overglaze are prepared; (2) glazing is conducted; and (3) a blank is fired. Under the conditions of the components, raw materials and the preparation method, the copper-series flambed glaze can be prepared, the further demand of people for the color of the flambed glaze is met, as for the copper-series flambed glaze, the dissolving-out amount of lead and cadmium is not detected, the copper-series flambed glaze can be used as adecoration of tea-tasting tea sets and daily tableware and is very safe, and the health of people is ensured.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a method for manufacturing copper-based kiln-transformed glaze. Background technique [0002] Ceramic kiln-changing glaze is one of the decoration techniques for ceramic surfaces. It has many changes, rich colors, and the most complicated shape. In ancient my country, most of the kiln-changing glazes were obtained by chance. They were very unstable and difficult to be controlled by people, so it is called It is called "Kiln Change", and the saying goes "Kiln Change is unparalleled", which means that it is unpredictable and unique. [0003] With the deepening of people's understanding of kiln-changing glaze, the beauty of kiln-changing defects has gradually been loved by people, so it is regarded as artistic enamel and appreciated by people. Especially in recent years, kiln-changing glaze can be used on daily tableware to make artistic ceramics practical Chemical use ...
